[Dovecot] Question: contention with blackberry
My production imap is currently UWIMAP with mbox.. One of the problems commonly observed is mailbox lock loss, which happens when: a) a VIP has multiple secretaries accessing a single mailbox (actually, they are professional enough to have figured the realities of conflicting access and rarely have a problem), b) somebody leaving their machine on at home and coming in and firing up their work computer c) important people with Blackberries....and the BB service polls the mailbox every so often and breaks the lock. In any case, the maillog ends up with a message like this:
May 5 19:45:04 mercury mail:info imapd[2035774]: Logout user=xxxxx host=bda056.bis.na.blackberry.com [216.9.249.56] May 5 19:46:52 mercury mail:info imapd[2502902]: Killed (lost mailbox lock) user=xxxxx host=cpe-24-161-103-11.hvc.res.rr.com [24.161.103.11] How will this work with Dovecot? I regard what is happening now as OK, working as designed. Although we may eventually move to a different mailbox format, I am only switching from UW to DC in the first step.

Honestly, moving to Maildir will solve all your problems with (a) and (b), and most likely (c) as well. Especially with (a), you would be doing your VIP's people a huge favor by converting to Maildir during your IMAP daemon move...

None of these are a problem with Dovecot. It supports multiple
connections accessing the same mbox. I'm still using mboxes myself
(going to move to dbox some day) and I've my desktop and my laptop
accessing the same mboxes just fine.
