In you first email to this thread it says:

So imap is crashing and even dumping a core.
Also I must disagree with your mbox+procmail statement. mbox has always been
very unoptimised mailbox format and everyone should be emphasised not to use it.
Also that combination has always had problems with indexing and file locking. I
would not use it on high volume mailservers. Or even medium volume mailservers.
