Hello, I'm preparing to convert from qpopper + UW-IMAP to dovecot. So far testing has gone very well. One problem we haven't figured out is that long-running POP sessions keep the mailbox locked, so that the MDA times out while trying to deliver.
We see this as well with mbox and pop3 accesses where some pop3 clients do not logout (iphone's are the worst offenders) for 30-90 minutes it seems.

We are having the same problem. It's not a problem with imap, only with pop3.
Timo,
Do you think the "idle process holds a lock open forever" problem that you recently patched for pop3 could also affect imap?
I've started to get some reports of customers' local mail delivery being hung up by imap processes now, and not just pop processes as we saw previously.
