IMAP/POP dead after upgrade to Plesk 7.5.4

[madsere]

After upgrading Plesk to 7.5.4 suddenly it was impossible to login to Horde.

Checking around I found there was no IMAP on port 141 as required by IMP (according to https://server/horde/imp/test.php)

Checking Plesk -> Server -> Services shows POP/IMAP to be stopped. Clicking the [>] start button fails to produce any result.

/var/log/messages report:

imapd.rc suggests starting IMAPD on port 143.

What is this mess?

Make sure that you do not have the courier-imap service in xinetd, this can cause the above behaviour.

Spot on! That was the problem, Thanks!

How could this happen? I'm certain I didn't enable them!
