Hi martijnbakker,

sometimes it helps to switch to another MTA and re-changing back to the initial one to solve issues ( cause might be: missing patches, unfinished updates/upgrades... ):

/usr/local/psa/admin/sbin/autoinstaller --select-release-current --install-component postfix

/usr/local/psa/admin/sbin/autoinstaller --select-release-current --install-component qmail
​

If this didn't fix your issues, please try the bootstrapper - repair procedure:

/usr/local/psa/bootstrapper/pp12.0.18-bootstrapper/bootstrapper.sh repair​

Well, it runs on productions servers, so no possibility to "just" switch to another MTA. But these message i also get on Debian 7 systems with Plesk 12. All clean installs.

Also with the bootstrapper repair problem persists.

Hi martijnbakker,

you will never get to know, if the suggested work-around, switching to postfix and backwards to qmail, might solve your issue, if you don't even try it.

Just to be sure, how long a downtime during the switches might be, I just did this two commands on two different servers and stopped 2 minutes and 12 seconds for server 1 and 1 minute and 58 seconds for server 2... I think this is a really short downtime, which still guarantees an all over 99,99 % uptime for your server.

Have tried it on a clean server, but no luck. I dont work that way, if something goes wrong with the switches. But i have never seen something like "journal: plesk sendmail" in my maillogs, which indicates it is something from within Plesk? And possible has nothing to do with qmail or postfix?
