Package: courier-mta
Version: 1.0.6-1
Severity: critical
Justification: causes serious data loss
Dear Maintainer,
* What led up to the situation?
I have made dist-upgrade from 9 to Debian 10
* What exactly did you do (or not do) that was effective (or
ineffective)?
Just upgraded the system. Courier MTA apparently randomly stops and cannot
be restarted.
This includes courier-imap-ssl
If I use web administrationa and click SAVE on IMAP or incoming ESMTP, and
install new configuration, services start working.
If I just use service courier-imap-ssl start this does not work, even if
service is enabled.
Example for courier-imap-ssl
I have restarted from web administration, so this works:
Executing /usr/sbin/imapd-ssl stop ; . /etc/courier/imapd-ssl ; test
"$IMAPDSSLSTART" != YES || /usr/sbin/imapd-ssl start...
Executing /usr/sbin/imapd stop ; . /etc/courier/imapd ; test "$IMAPDSTART" !=
YES || /usr/sbin/imapd start...

Now if I do following:
root@stw1:/tmp# service courier-imap-ssl stop
root@stw1:/tmp# service courier-imap-ssl start
root@stw1:/tmp# lsof -i :993
root@stw1:/tmp#
This does not work.

Hint: Some lines were ellipsized, use -l to show in full.
So if I do simple:
/usr/sbin/imapd-ssl start
This works.
It broke my email system and I need to install third party supervision to make
sure that services are running.
