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're using "maildrop" as
our MDA if that matters.
We don't see this issue for dovecot IMAP sessions. During long-running
IMAP sessions, incoming messages are deilvered tot he user's INBOX
without delay. But with POP, the MDA times out and the messages go
back to sendmail's queue for later delivery.
We though this setting would address the issue:
# Keep the mailbox locked for the entire POP3 session.
pop3_lock_session = no
But it doesn't seem to.
Any ideas?
Here is our "dovecot -n":
