Well! Very, very strange behaviour that I can’t explain : the
/tmp/sendmail-stdin filled by tee is fulfilled all the time, but when I
encounter the bug, nothing appear in the file!
Can you modify the script (and go back to sendmailpipe) with this added
line?
echo "=== START $$" >> /tmp/sendmail-lsof
lsof -d^mem,^cwd,^txt,^rtd -a -p $$ >> /tmp/sendmail-lsof
echo "=== END $$" >> /tmp/sendmail-lsof
and then send us the output when you encounter the problem?

Thank you for your concern Thomas.
Here is the modified script :
#!/bin/bash
TMP_FILE=“/tmp/sendmail-stdin”
TMP_LSOF_FILE=“/tmp/sendmail-lsof”
DATUM=“date +%Y%m%d-%H%M%S”
echo “=====NEW SENDMAIL CALL=======” >> “${TMP_LSOF_FILE}”
echo “${DATUM}” >> “${TMP_LSOF_FILE}”
echo “=== START $$” >> “${TMP_LSOF_FILE}”
lsof -d^mem,^cwd,^txt,^rtd -a -p $$ >> “${TMP_LSOF_FILE}”
echo “=== END $$” >> “${TMP_LSOF_FILE}”
echo “=====NEW SENDMAIL CALL=======” >> “${TMP_FILE}”
echo “${DATUM}” >> “${TMP_FILE}”
echo “========MESSAGE BEGIN========” >> “${TMP_FILE}”
exec tee -a “${TMP_FILE}” | /usr/sbin/sendmail.real “$@”
echo “========MESSAGE ENDED========” >> “${TMP_FILE}”
echo “${DATUM}” >> “${TMP_FILE}”
echo “======END SENDMAIL CALL======” >> “${TMP_FILE}”
Here are the “sendmail-stdin” log, showing a bad behavior, for 3 mails in a
row :
=====NEW SENDMAIL CALL=======

========MESSAGE BEGIN========
========MESSAGE ENDED========

And here is the “sendmail-lsof” of the corresponding messages :

I returned to SMTP until sendmailpipe work again…

What does the sendmail-lsof file look like for a successful invocation
of sendmail?

On a working sendmail call, it looks like this :

On a non-working sendmail call, we have only one “pipe” process :

Hello Thomas,
You’ll find our configuration in HTML format in the attached zip.
I hope you’ll find something interesting…

The module versions I was looking for seem fine, however I notice you
have OTRS loaded in the same mod_perl instance. I bet OTRS and RT step
on each other’s toes. If you add:
PerlOptions +Parent
to your RT virtualhost’s block, does that help?

Yes… Yet another test plateform that came into production without being
-at least- cleaned.
I bet OTRS and RT step
on each other’s toes.
If you add:
PerlOptions +Parent
to your RT virtualhost’s block, does that help?
Well, at least, now I don’t have any OTRS references in the configuration
page, but the real result will be available tomorrow.
I’ll let you know. Thank you very much for your help.

Hello Thomas, hello list.
I’m happy to say that the problem seems to be solved : today, not a single
sendmail error.
Thank you very very much Thomas.
