Old imapd problem

[Icheb]

Since yesterday I've been having a problem with the Imap service on just one domain.
It refuses to delete mail, change statusses etc. I am able to copy mail to a non-Inbox directory, and that works like a charm, however, the inbox is quite important.

I, however, am able to login by pop3 and delete everything, that way it's actually gone, but this is no solution.

Does anyone have an idea how this can be fixed ?
The permissions are rw for the user and the group owning the mailbox. I've also made it world read/write for test purposes, but this had no effect.

Does anyone know how to fix something like this ?

edit:
Migrating to the new system sounds nice, but is not something I want to do on this server. There's just too much imap users to do it.

It used to work great, but now it doesn't work at all...

Fixed the problem.

It appeared something like a zombie session was still running for the imap user. When I attached it to an strace, it was just waiting and sitting there for input.

After it was killed, everthing worked fine again.

So if this would ever happen to you, you've used an stunnel thingy and the stunnel session died. After that the imapd remained for some reason. Locate by using:
ps -ef | grep imapd
Verify that the users using it aren't online, if there's still something alive, kill it .
