[fetchmail-users] Exchange server and attachment

[Andres B. <an...@ba...>]

Dear all,
I'm fetching my email from an exchange server and I have regular
problems with the attachments. Attachments are often corrupted.

I have read the FAQs and apparently there are some known problems, and
the suggested solution is to change email server. Which of course I
can't because is not in my control.

I was wondering:
-if the FAQ entry is updated, and if there are still known problems
-if it might be a configuration problem on my side.

This is the output of fetchmail -V

This is fetchmail release 6.3.4+SSL+NLS.

It would help to see the .fetchmailrc and the output of "fetchmail -v
-v" showing a pull of a "corrupt" attachment.

Confirmation that a normal client (such as Thunderbird) can download a
mail without corruption of attachments would be useful (using the same
host as you're running fetchmail on, using the same config).

Hi,
could you explain a bit more what you mean? If I run the command I do
not see any output, nor there is any tput in /var/log/messages.

Yes, I can confirm you that I can read the email from Thunderbird.

Thanks in advance for your help,
	Andres

Please post your .fetchmailrc.

For the first, try "fetchmail --nosyslog -v -v".  It's likely you're
logging to syslog if there is not output on stdout.

On the host you're running fetchmail on?

Hi,
here is my configuration file:

set postmaster "an...@ba..."
set bouncemail
set daemon 60
set syslog

poll *******
     protocol imap
     port 993
     user '****'
     pass '****'
     is and...@ba...
     ssl
     keep

no output again...

I have limits in the amount of space I can use in my work address. So I
run fetchmail to get my mail from my work address to my personal server.
And then I connect from other hosts to read the email.

Connecting to my work server works with thunderbird, both on windows and
on Linux.

Hope

Right, you'll need to disable daemon mode too:

fetchmail --nosyslog -d0 -v -v

Thanks, that at least suggests a problem with the interaction of
fetchmail and exchange.  Hopefully once you manage to get the output
requested, showing a corrupt attachment download, we'll be able to
narrow down the problem.

Andres,

Rob didn't know about the "set daemon 60" option which sends output to
/dev/null. You can override that option with with "-d0" or "--daemon 0"
on the command line, or, if you want to leave fetchmail in daemon mode,
the "--nodetach" (-N) option keeps output on your screen while in daemon
mode. (With syslog enabled, i. e. omitting the --nosyslog, the mail log
file, often /var/log/mail or /var/log/maillog, will contain that
information -- perhaps you need to tell syslog via /etc/syslog.conf to
capture mail.debug logging.)

Rob,

I have adjusted the G3 item of the FAQ <http://www.fetchmail.info/fetchmail-FAQ.html#G3>
to suggest "--nosyslog --nodetach -vvv"
(option merging is safe BTW since fetchmail ships a copy of GNU getopt,
so the comand line capabilities do not depend on system libraries).

Well, fetchmail appears to be doing something differently than
Thunderbird then. The new command line ("fetchmail --nosyslog -Nvv" or 
"fetchmail --nosyslog -vvd0") will hopefully provide us with some detail.

yes?

HTH,
