Attached is an updated patch which adds this option to fetchmail.man

Any comments, please?

Thanks
Joe

I am attaching a patch to add a --startnum option to fetchmail. This
enables fetchmail to start downloading from the specified message
number instead of from the first message. This helps with flaky SMTP
connections where the connection is closed after a certain number of
messages are downloaded.

This is my first patch to fetchmail. Please let me know if there is a
better way of going about this.

Below is further explanation of my issue.

Subject: fetchmail downloading with message number as a parameter

Hello,

I am using fetchmail to download from my hotmail account.

It downloads a hundred or so emails and the connection dies. It does
this every time. I have the "keep" option set so it keeps downloading
the first emails again and again.

I am trying to figure out if I can tell fetchmail to download a
certain message number or range of message numbers.

Any thoughts or other alternative ideas that I can try, please?

Thanks
Joe

For fetchmail 7 some more sophisticated configuration can be done, so
thanks for that (I've added this to TODO-7.0).

I will not change that for 6.X releases though.

Noticed a situation where sslcertck on an expired cert
is preventing access even though I've specified a fingerprint.

This happens often when the service provider is up and
running just fine, but their management failed to plan for
cert renewals. End result, lock yourself out of mail till the
service renews, or lose both sslcertck and fingerprint
security to regain mail access. Not an ideal situation,
especially over hostile networks.

IMO, if a user has specified a cert fp, yes, please warn if
any other cert check fails, but do not error out. Or at least
make warn the default action, and erroring out a configurable
option.

It compiles against openssl 1.0.1e fine, will test when I can.

autoreconf -fiv adds a missing ./test-driver to the distribution.

>From a quick read of NEWS and man diff...

- sslprotocolversion
Counter to fm manpage, openssl supports through TLSv1.2 since 1.0.1.
So perhaps AUTO should have/doc a version order/pref/default in
there now. And have 1.x options. I don't know much on that to say
(other than noting the apparrent tls.bigger_num -> ssl3 history in
reverse).

Ssl/tls version was separate from the socket(wrapped)/starttls init
point anyway afaik so this breakout is nicer.

If fm is doing auto negotiations of things, its debug mode should
print whatever was finally agreed upon as confirmation and for later
use in fixed mode.

Maybe shorten to 'sslprotover'.

- sslmode
Man page: this is a subparameter, not the entire option, so...
change from
 starttls=may: this option is implicity upgraded to starttls=must.
to
 starttls=may: if starttls=may is specified, it is implicitly
 upgraded to starttls=must.

At the top in this man, starttls=may is *not* the default if below
at that subparameter sslcertck is also default thus forcing
starttls=must.

- sslcertck -> starttls default, wrapped legacy
I agree starttls is the 'new way' but the installed server base
merits retaining wrapped as the default on the standalone ports.
ie: how often does one see starttls on (25/110/143) advertised.
Wrapped was interim crypto till starttls could be implemented, but
now it seems used to guarantee buggy/partial/cleartext implementations
are never used.

- I presume this sort of custom ability still exists as needed:
service 465 + protocol imap + sslmode none

- sslcertck / sslfingerprint
These two sections mention failing regardless of the other. That
is good for high combined security [1], but I think there may be a
conflict... there may be a case, perhaps in a corporate thing, where
the signing cert isn't available but the print is documented. You'd
want the print to pass it and the certcheck (in the presence of a
print) to have a tri-option like...
sslcertck = abort | warn | off

[1] With 6.3.26 I still use both sslcertck (with an add upon need
from empty systemwide subject hashed certs dir) and sslfingerprint.
People can go further with only a certfile/certpath per server.

- Some people might want to use OCSP. Perhaps even when using cert
prints, checkfiles, etc... to alert them to some management or risk
issue for which the apparent server cert hasn't been changed out
yet. Firefox has an example OCSP preferences panel. CRL/OCSP is
maybe only mentioned as an aside in the man page, without saying
what CRL/OCSP and other verification/validation process/parameters
are checked with certs. That is maybe in the SSL README's, didn't
look.

sslremotecheck ocsp = abort | warn | off
sslremotecheck crl = abort | warn | off

A similar model may be thought of regarding any certificate
observatories / transparencies that may be coming online.

sslremotecheck observ = abort | warn | off

- sslcertfile
Man says 'in addition to sslcertpath' twice.

My 2013/07/28 note about PFS had some examples for people
to see what their server works with. Some more links:
https://en.wikipedia.org/wiki/Transport_Layer_Security
https://en.wikipedia.org/wiki/Comparison_of_TLS_Implementations

- pidfile /dev/null

Sometime back there was early talk on parallel. I run some things
in parallel. A simple disable key would be nice. Right now it's in
form of: --pidfile $(mktemp ...), which is actually further wrapped
in shell to check mktemp before fm exec. /dev/null doesn't work there
but would suffice as key to avoid open/write/unlink and allow para.

Greetings,

in an effort to get sufficient testing, I have released the next alpha
version of fetchmail 7.0.0. This merges post-6.3.23 changes in, and
should have all relevant fixes from releases up to, and including, 6.3.26.

The notable changes beyond that are

1. cleanup and change of SSL options to make them easier to understand,
and separate concerns (the protocol no longer overloads the connection
mode), and enable sslcertck by default (this should all be in the manual
page already, if bits are missing, let me know)

2. the addition of an option to print the SSL cipher in verbose mode,
and the ability to specify the offered ciphers through the environment
variable FETCHMAIL_SSL_CIPHERS. This is only documented here and in the
NEWS file for now.  There are several SSL/TLS code cleanups I need to
make before adding this feature formally, and on a per-server basis.

   Example:

   env FETCHMAIL_SSL_CIPHERS='ECDH:DH:!MEDIUM:!LOW:!EXP' fetchmail -vv

Note that fetchmail continues to be very chatty in debug mode (with two
-v options, or a -vv option), and note that some popular services
(Microsoft's and O2, for one) fail to set up a connection with the
setting above, whilst some others (notably, Google, Yahoo!,
Domainfactory) are happy with DH.

I am soliciting feedback on the new SSL option design and use, and yes I
know that certificate pinning, multiple certificate fingerprint, SHA1
certificate fingerprint checking are still pending.

The alpha version is available for download from these sites:
<http://home.pages.de/~mandree/fetchmail/>
<https://sourceforge.net/projects/fetchmail/files/branch_7-alpha/>

It is not available for download from BerliOS, its file release system
is too cumbersome to use for non-formal previews.

The fetchmail sources are also available via Git.

The corresponding git tag is SNAPSHOT_7-0-0-alpha5, the branch is
"sslrevolution1". The repository browsers (these show the clone URLs):
<http://gitorious.org/fetchmail>
<http://git.berlios.de/cgi-bin/cgit.cgi/fetchmail/>
<http://git.berlios.de/cgi-bin/gitweb.cgi?p=fetchmail;a=summary>

Please send feedback to fet...@li....

Happy fetches!

Andy,

thank you for taking the initiative.

The existing IDLE code is very intrusive (not to say ugly) and fragile,
as you have probably noticed, and I would much rather toss it out rather
than extend it.  That does not mean I want to abolish the feature, but
just the implementation.

The whole machinery will have to undergo revision in order to support
client-side IMAP "seen" status tracking without need to tamper with the
flags, and in order to support PIPELINING.

These syscalls have a history of not working properly, too, so the
implementation means is a moot point.

The main issue with concurrent polls is that some parts of the code
(notably the SSL socket code as well as the sink) use global variables.

Without having looked at your code yet (ENOTIME):

That data might be a disconnect because we've been idling too long, to
mark the most obvious failure case.  I am not so sure that caching
connections between polls is a workable, and that the ratio of effort
and outcome is right.  NOTIFY might give more benefit for the same effort.

I have a feeling that any attempts to patch up the current IDLE code
structure is spending efforts in the wrong places.

I think a more radical approach to the overall poll setup and action is
warranted, one that does not put one layer of context (through global
variables, struct query, hostdata, whatever) over the next, which is all
laid out differently, and is likely getting in the way of cached
connections, too.

I think the end will more look like a collection of objects.  There is
no new design specification for fetchmail yet, however.

Hi, I've been looking into adding support for polling more than one
server using the IMAP IDLE feature. I'm very new to the fetchmail source
code, so any suggestions or comments would be helpful :)

Currently, IDLE support is implemented in the imap_getrange function by
blocking the getrange call until new messages are available. Afterwards,
it forces a repoll and repeats the process waiting for new messages. The
down side of this is that it starves out all the other servers because
the IMAP do_session never returns (except on errors).

From what I understand, many people have expressed concerns about
polling multiple servers concurrently and I agree that using threads or
forks would be a bad idea. However, we should be able to use poll(2) or
select(2) to accomplish the same thing without the threading issues. As
it turns out, fetchmail uses select to implement it's interruptible_idle
function anyway.

I've put up a working prototype for polling multiple servers here if
anyone is interested in taking a look at it. Please treat it with some
skepticism though, it still needs a lot of work ;)

    http://pileus.org/git/?p=~andy/fetchmail;h=idle

The basic idea is that the blocking getrange is removed and the servers
socket is saved between polls and passed to select() so that fetchmail
can wake up when new mail arrives.

I added two new functions to the 'struct method' table that replace the
existing, internal, imap_idle function:

  start_idle:  called at the end of a fetch, this puts the connection in
               IDLE mode so that we can wake up when mail arrives

  finish_idle: called at the start of the next poll, resets the
	       connection to 'normal mode'

There's also a couple additions to 'struct hostdata' (I don't know if
this the correct structure to use, but it seems to work).

  true_idle:   set to TRUE if the server supports IDLE polling,
               otherwise we may need to fake it somehow

  idle_socket: the socket saved between polls, the connection setup and
	       destruction in do_session is skipped while idling

  idle_ready:  set to TRUE after calling select() if data is available
               for reading on the socket

Whew, I hope that wasn't too long, I'll keep poking around at this
during the next few weeks and see if I can clean it up a bit. I thought
it would be good to give the other developers a heads up though.

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

Comment:
Your fetchmail behaves properly, sets a umask of 077, runs open(..., 0666) which should end up with a mode 0600 file according to various standards (including traditional Unix behaviour), yet the resulting file permissions are 0640. 

It looks as though the umask call was ignored and as though the system had retained the original 027 umask for file creation. The system is broken and in violation of decade-old standards. This is a kernel or libc bug affecting umask() and open(), and nothing fetchmail could do anything about.

If you have a choice of kernel and/or libc versions, try different ones, if you can't or that does not help, take this up to the server's provider.

I am now closing this bug.

The .fetchids have the permissions rw-r-----
after this.

My normal startscript is this:
-------------------- snip -----------------
#!/bin/bash
cd /kunden/xxxxxx_xxxxx/
bin/fetchmail -f .fetchmailrc
chmod 600 .fetchids
------------------- snip -----------------

The last line is my workaround.

And the binary have been compiled on the same maschine. No compiler warnings.

Comment:
Please run:

env LC_ALL=C strace -etrace=file,umask fetchmail -Nd0

and see what you get.  You should be seeing something like:

...
umask(077)                              = 0...
...
unlink("/home/mandree/.fetchids_")      = -1 ENOENT (No such file or directory)
open("/home/mandree/.fetchids_", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
rename("/home/mandree/.fetchids_", "/home/mandree/.fetchids") = 0
unlink("/home/mandree/.fetchids_")      = -1 ENOENT (No such file or directory)
open("/home/mandree/.fetchids_", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
rename("/home/mandree/.fetchids_", "/home/mandree/.fetchids") = 0
unlink("/home/mandree/.fetchmail.pid")  = 0

And in that situation, the .fetchids permissions will be 0666 & ~077 == 0600.

If that is not the case, check the way how fetchmail is being started, if the start script modifies the .fetchids permission; and if that is not the case, kernel bugs are to be suspected; note that the Kernel has Xen/Paravirtualization and GRSecurity patches applied.

Have you compiled fetchmail on the same computer?
Were there any compiler warnings beyond non-constant format strings?

Comment:
Thank you.

Regarding the system, lsb_release -a might shed some light, but I do not think this relevant here.

Based on your logs, I have revisited relevant source code, and fetchmail does not set the permissions explicitly. It uses the fopen() function, which is documented to set mode 0666 &= ~(process_umask). Fetchmail sets the umask to 077 after opening the log file, so the resulting idfile (.fetchids) mode is 0600 (octal) meaning only the user has read/write permissions, nothing more.
This works for me or others at least on Solaris 10, FreeBSD, NetBSD, Linux, Cygwin (on NTFS file systems).

I am now suspecting that the filesystem hosting your .fetchids file is to blame here (read: insufficient) and does not offer UNIX-standard permissions.

Can you try running:

env LC_ALL=C df -P -T /kunden/xxxxxx_xxxxx/.fetchids 

This should (by way of -T) shed some light on the file system type, for me it looks like this on Linux

$ LC_ALL=C df -P -T .fetchids 
Filesystem                Type 1024-blocks      Used Available Capacity Mounted on
/dev/mapper/vgcrypt0-home ext4   182636724 145107628  35673608      81% /home

and like this on FreeBSD:

$ LC_ALL=C df -P -T .fetchmailrc 
Filesystem      Type 512-blocks     Used     Avail Capacity  Mounted on
/dev/label/usr  ufs   174671692 53919452 106778508    34%    /usr

Meaning Linux resides on ext4, FreeBSD on ufs.

If you can figure out the mount options and show it, that would also help; "mount -v /usr" (or whatever is in the rightmost column) should do that.

Comment:
1. My operating system:

It is a management Server from Domainfactory. I can not see with os version. But it looks like an gentoo linux.

2. Compiler Version:
I build it from source with gcc 4.4.5

3. SMTP listener or MTA
I forward it to the DF Mailsystem and I don't exaktly
know what it is.

4. command line options:
None. Everything in .fetchmailrc

5.  env LC_ALL=C fetchmail -V:

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

The .fetchids have the permissions rw-r-----
after this.

My normal startscript is this:
-------------------- snip -----------------
#!/bin/bash
cd /kunden/xxxxxx_xxxxx/
bin/fetchmail -f .fetchmailrc
chmod 600 .fetchids
------------------- snip -----------------

The last line is my workaround.

And the binary have been compiled on the same maschine. No compiler warnings.

Comment:
Please run:

env LC_ALL=C strace -etrace=file,umask fetchmail -Nd0

and see what you get.  You should be seeing something like:

...
umask(077)                              = 0...
...
unlink("/home/mandree/.fetchids_")      = -1 ENOENT (No such file or directory)
open("/home/mandree/.fetchids_", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
rename("/home/mandree/.fetchids_", "/home/mandree/.fetchids") = 0
unlink("/home/mandree/.fetchids_")      = -1 ENOENT (No such file or directory)
open("/home/mandree/.fetchids_", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
rename("/home/mandree/.fetchids_", "/home/mandree/.fetchids") = 0
unlink("/home/mandree/.fetchmail.pid")  = 0

And in that situation, the .fetchids permissions will be 0666 & ~077 == 0600.

If that is not the case, check the way how fetchmail is being started, if the start script modifies the .fetchids permission; and if that is not the case, kernel bugs are to be suspected; note that the Kernel has Xen/Paravirtualization and GRSecurity patches applied.

Have you compiled fetchmail on the same computer?
Were there any compiler warnings beyond non-constant format strings?

Comment:
Thank you.

Regarding the system, lsb_release -a might shed some light, but I do not think this relevant here.

Based on your logs, I have revisited relevant source code, and fetchmail does not set the permissions explicitly. It uses the fopen() function, which is documented to set mode 0666 &= ~(process_umask). Fetchmail sets the umask to 077 after opening the log file, so the resulting idfile (.fetchids) mode is 0600 (octal) meaning only the user has read/write permissions, nothing more.
This works for me or others at least on Solaris 10, FreeBSD, NetBSD, Linux, Cygwin (on NTFS file systems).

I am now suspecting that the filesystem hosting your .fetchids file is to blame here (read: insufficient) and does not offer UNIX-standard permissions.

Can you try running:

env LC_ALL=C df -P -T /kunden/xxxxxx_xxxxx/.fetchids 

This should (by way of -T) shed some light on the file system type, for me it looks like this on Linux

$ LC_ALL=C df -P -T .fetchids 
Filesystem                Type 1024-blocks      Used Available Capacity Mounted on
/dev/mapper/vgcrypt0-home ext4   182636724 145107628  35673608      81% /home

and like this on FreeBSD:

$ LC_ALL=C df -P -T .fetchmailrc 
Filesystem      Type 512-blocks     Used     Avail Capacity  Mounted on
/dev/label/usr  ufs   174671692 53919452 106778508    34%    /usr

Meaning Linux resides on ext4, FreeBSD on ufs.

If you can figure out the mount options and show it, that would also help; "mount -v /usr" (or whatever is in the rightmost column) should do that.

Comment:
1. My operating system:

It is a management Server from Domainfactory. I can not see with os version. But it looks like an gentoo linux.

2. Compiler Version:
I build it from source with gcc 4.4.5

3. SMTP listener or MTA
I forward it to the DF Mailsystem and I don't exaktly
know what it is.

4. command line options:
None. Everything in .fetchmailrc

5.  env LC_ALL=C fetchmail -V:
(xxxx for anon)

Thank you for taking the time to report this problem.

However, we need further information in order to be able to 
investigate and eventually fix the problem.

Please see http://fetchmail.info/fetchmail-FAQ.html#G3 for a 
checklist of pieces of information that you need to report.

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

Please run:

env LC_ALL=C strace -etrace=file,umask fetchmail -Nd0

and see what you get.  You should be seeing something like:

...
umask(077)                              = 0...
...
unlink("/home/mandree/.fetchids_")      = -1 ENOENT (No such file or directory)
open("/home/mandree/.fetchids_", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
rename("/home/mandree/.fetchids_", "/home/mandree/.fetchids") = 0
unlink("/home/mandree/.fetchids_")      = -1 ENOENT (No such file or directory)
open("/home/mandree/.fetchids_", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
rename("/home/mandree/.fetchids_", "/home/mandree/.fetchids") = 0
unlink("/home/mandree/.fetchmail.pid")  = 0

And in that situation, the .fetchids permissions will be 0666 & ~077 == 0600.

If that is not the case, check the way how fetchmail is being started, if the start script modifies the .fetchids permission; and if that is not the case, kernel bugs are to be suspected; note that the Kernel has Xen/Paravirtualization and GRSecurity patches applied.

Have you compiled fetchmail on the same computer?
Were there any compiler warnings beyond non-constant format strings?

Comment:
Thank you.

Regarding the system, lsb_release -a might shed some light, but I do not think this relevant here.

Based on your logs, I have revisited relevant source code, and fetchmail does not set the permissions explicitly. It uses the fopen() function, which is documented to set mode 0666 &= ~(process_umask). Fetchmail sets the umask to 077 after opening the log file, so the resulting idfile (.fetchids) mode is 0600 (octal) meaning only the user has read/write permissions, nothing more.
This works for me or others at least on Solaris 10, FreeBSD, NetBSD, Linux, Cygwin (on NTFS file systems).

I am now suspecting that the filesystem hosting your .fetchids file is to blame here (read: insufficient) and does not offer UNIX-standard permissions.

Can you try running:

env LC_ALL=C df -P -T /kunden/xxxxxx_xxxxx/.fetchids 

This should (by way of -T) shed some light on the file system type, for me it looks like this on Linux

$ LC_ALL=C df -P -T .fetchids 
Filesystem                Type 1024-blocks      Used Available Capacity Mounted on
/dev/mapper/vgcrypt0-home ext4   182636724 145107628  35673608      81% /home

and like this on FreeBSD:

$ LC_ALL=C df -P -T .fetchmailrc 
Filesystem      Type 512-blocks     Used     Avail Capacity  Mounted on
/dev/label/usr  ufs   174671692 53919452 106778508    34%    /usr

Meaning Linux resides on ext4, FreeBSD on ufs.

If you can figure out the mount options and show it, that would also help; "mount -v /usr" (or whatever is in the rightmost column) should do that.

Comment:
1. My operating system:

It is a management Server from Domainfactory. I can not see with os version. But it looks like an gentoo linux.

2. Compiler Version:
I build it from source with gcc 4.4.5

3. SMTP listener or MTA
I forward it to the DF Mailsystem and I don't exaktly
know what it is.

4. command line options:
None. Everything in .fetchmailrc

5.  env LC_ALL=C fetchmail -V:
(xxxx for anon)

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

Comment:
Thank you.

Regarding the system, lsb_release -a might shed some light, but I do not think this relevant here.

Based on your logs, I have revisited relevant source code, and fetchmail does not set the permissions explicitly. It uses the fopen() function, which is documented to set mode 0666 &= ~(process_umask). Fetchmail sets the umask to 077 after opening the log file, so the resulting idfile (.fetchids) mode is 0600 (octal) meaning only the user has read/write permissions, nothing more.
This works for me or others at least on Solaris 10, FreeBSD, NetBSD, Linux, Cygwin (on NTFS file systems).

I am now suspecting that the filesystem hosting your .fetchids file is to blame here (read: insufficient) and does not offer UNIX-standard permissions.

Can you try running:

env LC_ALL=C df -P -T /kunden/xxxxxx_xxxxx/.fetchids 

This should (by way of -T) shed some light on the file system type, for me it looks like this on Linux

/dev/mapper/vgcrypt0-home ext4   182636724 145107628  35673608      81% /home

and like this on FreeBSD:

$ LC_ALL=C df -P -T .fetchmailrc 
Filesystem      Type 512-blocks     Used     Avail Capacity  Mounted on
/dev/label/usr  ufs   174671692 53919452 106778508    34%    /usr

Meaning Linux resides on ext4, FreeBSD on ufs.

If you can figure out the mount options and show it, that would also help; "mount -v /usr" (or whatever is in the rightmost column) should do that.

Comment:
1. My operating system:

It is a management Server from Domainfactory. I can not see with os version. But it looks like an gentoo linux.

2. Compiler Version:
I build it from source with gcc 4.4.5

3. SMTP listener or MTA
I forward it to the DF Mailsystem and I don't exaktly
know what it is.

4. command line options:
None. Everything in .fetchmailrc

5.  env LC_ALL=C fetchmail -V:

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

Thank you.

Regarding the system, lsb_release -a might shed some light, but I do not think this relevant here.

Based on your logs, I have revisited relevant source code, and fetchmail does not set the permissions explicitly. It uses the fopen() function, which is documented to set mode 0666 &= ~(process_umask). Fetchmail sets the umask to 077 after opening the log file, so the resulting idfile (.fetchids) mode is 0600 (octal) meaning only the user has read/write permissions, nothing more.
This works for me or others at least on Solaris 10, FreeBSD, NetBSD, Linux, Cygwin (on NTFS file systems).

I am now suspecting that the filesystem hosting your .fetchids file is to blame here (read: insufficient) and does not offer UNIX-standard permissions.

Can you try running:

env LC_ALL=C df -P -T /kunden/xxxxxx_xxxxx/.fetchids 

This should (by way of -T) shed some light on the file system type, for me it looks like this on Linux

$ LC_ALL=C df -P -T .fetchids 
Filesystem                Type 1024-blocks      Used Available Capacity Mounted on
/dev/mapper/vgcrypt0-home ext4   182636724 145107628  35673608      81% /home

and like this on FreeBSD:

$ LC_ALL=C df -P -T .fetchmailrc 
Filesystem      Type 512-blocks     Used     Avail Capacity  Mounted on
/dev/label/usr  ufs   174671692 53919452 106778508    34%    /usr

Meaning Linux resides on ext4, FreeBSD on ufs.

If you can figure out the mount options and show it, that would also help; "mount -v /usr" (or whatever is in the rightmost column) should do that.

It is a management Server from Domainfactory. I can not see with os version. But it looks like an gentoo linux.

2. Compiler Version:
I build it from source with gcc 4.4.5

3. SMTP listener or MTA

know what it is.

4. command line options:
None. Everything in .fetchmailrc

5.  env LC_ALL=C fetchmail -V:

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

1. My operating system:

It is a management Server from Domainfactory. I can not see with os version. But it looks like an gentoo linux.

2. Compiler Version:
I build it from source with gcc 4.4.5

3. SMTP listener or MTA
I forward it to the DF Mailsystem and I don't exaktly
know what it is.

4. command line options:
None. Everything in .fetchmailrc

5.  env LC_ALL=C fetchmail -V:

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

Summary: Not the expected Length

Details: Mails receiving sometimes are marked with the error "not the expected length" (Hoster is 1und1) . The transfer is broken but the received fragment is being forwarded to the SMTP-Relais as long as the mail is not deletet at hte provider. There should be a new Parameter which does not checks the actual and expected size so that such "error-marked-mails" would be forwareded and then after the transfer should be deleted at the provider if the option is activated.

Summary: wrong permissions on .fetchids

Details: I have one fetchmail poll where I set 'keep' and 'no fetchall'.
After I start fetchmail the .fetchids-File have read-write owner and
read group. The next time fetchmail stops with the error that 
read-write-execute owner is the maximum allowed permissions.

I uderstand that fetchmail stops with wrong permissions, but thats the permission that it hase self set.

I use fetchmail 6.3.26.

Summary: IMAP IDLE + SSL: Error: re-poll failed

Details: I use fetchmail with SSL and IMAP IDLE. The IMAP connection freezes after some time and the re-poll failed after 28 min. It looks like there is a ssl socket timeout before a IMAP IDLE re-poll is issued.

Jan  3 20:59:35 mini2 fetchmail[14842]: Query status=2 (SOCKET)
-----

The re-poll does not fail, when the idle timeout is reduced from 28 min to 10 minutes. This should also fulfil the RFC 2177, because the RFC suggests to re-issue a IDLE command at LEAST every 29 minutes.

RFC 2177 

   "The server MAY consider a client inactive if it has an IDLE command
   running, and if such a server has an inactivity timeout it MAY log
   the client off implicitly at the end of its timeout period.  Because
   of that, clients using IDLE are advised to terminate the IDLE and
   re-issue it at least every 29 minutes to avoid being logged off.
   This still allows a client to receive immediate mailbox updates even
   though it need only "poll" at half hour intervals."

Other IMAP Clients uses a shorter IDLE re-poll timer or issues a NOOP Command.
Microsoft Outlook:  10 min
Apple Mail:  IMAP NOOP every 1 minute (RFC 3501: "The NOOP command can also be used to reset any inactivity autologout timer on the server.")

Hello Matthias,

I did a dtrace for the SSL case and non-SSL case. In both variants the  TCP KeepAlive is enabled.

199552      20     14 socket(0x2, 0x1, 0x6)		 = 5 0
199559       8      2 setsockopt(0x5, 0xFFFF, 0x8)		 = 0 0
199634   21589     72 connect(0x5, 0x7FAF0AC01320, 0x10)		 = 0 0

But there is an other difference:
The non-ssl socket uses the system call recvfrom to wait for data from the imap server during the idle time. The ssl socket uses the system call "read" to wait for data from the imap server during the idle time. The tcp stack sends no KeepAlive Packets during the system call read.

You can download  the complete dtrace files for both variants from https://www.hidrive.strato.com/lnk/RBTrVUhJ

Best regards,
Wolfgang

Wolfgang,

could you dtrace setsockopt and/or all socket option, for (1) the SSL case, (2) the non-SSL case?  I unconditionally enable SO_KEEPALIVE after the socket has been opened, and never see them disabled - perhaps your OpenSSL library behaves differently.

Best regards,
Matthias

Thanks for the detailed information.

However, this pretty much looks like a networking issue. The server just hung up, but there was no FIN|ACK handshake from closing down the connection, so fetchmail was not informed of the shutdown or close until it tried to send the next packet.

This pretty much looks like a networking issue, broken router or NAT or Masquerading. I'll grant that TCP keepalives might help.

Unfortunately, strato does not appear to support STARTTLS, so we cannot test that.

Also there is no network traffic during the idle time.  And the response for first packet TCP Push from fetchmail to the imap server is a Reset.

Now for me looks like the issue is, fetchmail opens the Socket for the SSL Session without a TCP KeepAlive.

When I use an unencrypted imap session, the TCP KeepAlive is active. The tcpdump shows the TCP KeepAlive packets during the imap idle time.

Wolfgang

Comment:
Have Strato fix their server timeouts instead, the 30 minute timer is a "MUST" clause in RFC-3501 section 5.4, see http://tools.ietf.org/html/rfc3501#section-5.4

If there is a socket timeout, I'd like to see an strace or truss trace proving it, and possibly an accompanying tcpdump or wireshark/tshark dump of the protocol with timestamps, to see when the connection gets closed. Chances are that there is a problem on your end - are you using IPv4 NAT or Masquerading?

Summary: IMAP IDLE + SSL: Error: re-poll failed

Details: I use fetchmail with SSL and IMAP IDLE. The IMAP connection freezes after some time and the re-poll failed after 28 min. It looks like there is a ssl socket timeout before a IMAP IDLE re-poll is issued.

-----

The re-poll does not fail, when the idle timeout is reduced from 28 min to 10 minutes. This should also fulfil the RFC 2177, because the RFC suggests to re-issue a IDLE command at LEAST every 29 minutes.

RFC 2177 

   "The server MAY consider a client inactive if it has an IDLE command
   running, and if such a server has an inactivity timeout it MAY log
   the client off implicitly at the end of its timeout period.  Because
   of that, clients using IDLE are advised to terminate the IDLE and
   re-issue it at least every 29 minutes to avoid being logged off.
   This still allows a client to receive immediate mailbox updates even
   though it need only "poll" at half hour intervals."

Other IMAP Clients uses a shorter IDLE re-poll timer or issues a NOOP Command.
Microsoft Outlook:  10 min
Apple Mail:  IMAP NOOP every 1 minute (RFC 3501: "The NOOP command can also be used to reset any inactivity autologout timer on the server.")

Hello Matthias,

I did a dtrace for the SSL case and non-SSL case. In both variants the  TCP KeepAlive is enabled.

199552      20     14 socket(0x2, 0x1, 0x6)		 = 5 0
199559       8      2 setsockopt(0x5, 0xFFFF, 0x8)		 = 0 0
199634   21589     72 connect(0x5, 0x7FAF0AC01320, 0x10)		 = 0 0

But there is an other difference:
The non-ssl socket uses the system call recvfrom to wait for data from the imap server during the idle time. The ssl socket uses the system call "read" to wait for data from the imap server during the idle time. The tcp stack sends no KeepAlive Packets during the system call read.

You can download  the complete dtrace files for both variants from https://www.hidrive.strato.com/lnk/RBTrVUhJ

Also there is no network traffic during the idle time.  And the response for first packet TCP Push from fetchmail to the imap server is a Reset.

Now for me looks like the issue is, fetchmail opens the Socket for the SSL Session without a TCP KeepAlive.

When I use an unencrypted imap session, the TCP KeepAlive is active. The tcpdump shows the TCP KeepAlive packets during the imap idle time.

Wolfgang

Comment:
Have Strato fix their server timeouts instead, the 30 minute timer is a "MUST" clause in RFC-3501 section 5.4, see http://tools.ietf.org/html/rfc3501#section-5.4

If there is a socket timeout, I'd like to see an strace or truss trace proving it, and possibly an accompanying tcpdump or wireshark/tshark dump of the protocol with timestamps, to see when the connection gets closed. Chances are that there is a problem on your end - are you using IPv4 NAT or Masquerading?

Summary: Relocating pidfile, FETCHMAILHOME, parallel

Details: I needed  to work around the lack of --password and also
fetch some things in parallel.

FETCHMAILHOME didn't seem to honor itself if set to an
empty writeable dir. [bug #1]

There was --pidfile, but it needed to be parallelizable to
avoid clobbering itself. By default it has no random part.
So --pidfile $(mktemp group1.pid.XXXXXX). [feat #1]

Looking to fix b#1 for others.
Note f#1 also applies to idfile, etc.

Comment:
The pid file is meant to be constant because it serves as a lock file.

FETCHMAILHOME works as advertised for me:

$ mkdir /tmp/empty
$ LC_ALL=C FETCHMAILHOME=/tmp/empty fetchmail -V

No mailservers set up -- perhaps /tmp/empty/fetchmailrc is missing?

If you have evidence to the contrary, please show me a way to reproduce the problem and reopen the bug report.

Summary: Man page table rendering, keywords

There seems to be some 'Keyword/Option Summary'

with the above nroff.

And from TODO, some projects use tables for this too.

Comment:
As the fetchmail.man comment banner at the top reveals, 
the roff source is meant to be preprocessed through tbl, i. e.

nroff -man -t fetchmail.man

And grog will also figure that out:

$ grog fetchmail.man 
groff -t -man fetchmail.man

Not a bug, closing report as invalid.

> I have one of mine constructed as, with n incremented

fetchmail -v -v -f fmrc -N -K -a -n user1@fqdn1

And with this I get one of these for each incremented entry
present...

"Old UID list from user1@fqdn1: <empty>"

20 entries, 20 of those emitted incrementally.
Not sure why, mentioning it in case it's buggy before
I forget to look more into it.

Just one of these: Scratch list of UIDs: <empty>
