[fetchmail-users] Fetchmail is running slow on Mac OS X

[Stéphane L. <ste...@lu...>]

Hi,

I hope, that this is the right place for my question regarding  
fetchmail:

I have switched my mailserver from linux to Mac OS X 10.4. I  
apreciated, that fetchmail was already included in  OS 10.4. But on  
OS X it takes 1-2 minutes for fetchmail to set up a connection:

When I start fetchmail, I get this message:

fetchmail: starting fetchmail 6.2.5 daemon
fetchmail: 6.2.5 querying ... (protocol IMAP) at Sat, 31 Dec 2005  
03:03:13 +0100 (CET): poll started

Then nothing happens for about one minute  (timout?), then fetchmail  
ist running normaly:

fetchmail: IMAP< * OK [CAPABILITY IMAP4REV1 LOGIN-REFERRALS STARTTLS  
AUTH=LOGIN] ...  03:04:11 +0100 (CET)
fetchmail: IMAP> A0001 CAPABILITY
fetchmail: IMAP< * CAPABILITY IMAP4REV1 IDLE NAMESPACE MAILBOX- 
REFERRALS BINARY UNSELECT SCAN SORT THREAD=REFERENCES  
THREAD=ORDEREDSUBJECT MULTIAPPEND LOGIN-REFERRALS STARTTLS AUTH=LOGIN

When I try to connect manualy, I get an answer at once:

mac-mini:/var/root root# telnet ... 143
Trying ... ...
Connected to ....
Escape character is '^]'.
* OK [CAPABILITY IMAP4REV1 LOGIN-REFERRALS STARTTLS AUTH=LOGIN] ...  
IMAP4rev1 2003.339 at Sun, 1 Jan 2006 23:47:33 +0100 (CET)

On my linux server it takes only a few seconds for fetchmail to check  
the mail accounts? What can I do? Is it a DNS or IDENT problem? I'm  
using a NAT router.


Kind regards,

Stephane

As per my message on the other list - please try 6.3.1.

Normally delays of a minute or two indicate a DNS problem somewhere.

Ah, ident could be a possibility too, depending on the server software, but 
DNS is more likely.

As the other Rob recommended, first try fetchmail 6.3.1 from 
http://fetchmail.berlios.de/.  If that doesn't help let us know.

What kind of DNS problem? Server or client? I can telnet to the port  
143 without a delay.

I have tried fetchmail 6.3.1. I still have the one minute delays for  
setting up a connection:

mac-mini:~/Desktop root# ./fetchmail -Nv -f /var/root/.fetchmailrc
fetchmail: WARNING: Running as root is discouraged.

Next thing to do is run fetchmail under truss to get a dump of what's
going on.  Watching that it should be fairly obvious where the problem
lies.  The output of that, with the area the pause occurs marked,
would help in tracking down the problem.

Here is the output of kdump:

...

12710 fetchmail CALL  sigaction(0xd,0xbfffd3d8,0xbfffd450)

Does this help in tracking down the problem?

Probably the same as <https://bugzilla.mozilla.org/show_bug.cgi?id=231607>.

Try this on your fetchmail 6.3.1 source directory (requires Perl installed):

perl -ple 's/([AP])F_UNSPEC/\1F_INET/g' -i.bak \
     checkalias.c driver.c env.c servport.c

Then rebuild and reinstall fetchmail 6.3.1 and let us know if the
problem is gone.

Merci.
