Description Sinan H 2005-01-18 12:59:25 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3)

Description of problem:
After upgrading our mail server (sendmail) from 2.6.9-1.667 to
2.6.10-1.741_FC3, sending mails with attachements >~10K hangs.
Same behaviour with every mail software (pine, mozilla,
thunderbird...) and host platform (winXX, *nix)
Works well when booted in 2.6.9

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.boot the mail server on 2.6.10
2.send a mail with attachement from an other host via smtp
3.progression hangs at about 90%

Actual Results:  Connection with the mail server is established but
stalls before the mail is completely transferred to the server

Expected Results:  send mail !

Additional info:

serverside, incoming sendmail request with attachement doesn't get
logged. Probably normal because transfer is never completed. 
Small mails (no attachement, or only small txt attached) works well,
log normal. Sendmail configuration looks innocent.

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

Fixed in 2.6.12-1.1381_FC3, though I dont have any idea how, why, what the hell etc.
Broken in lesser kernels.
