Thanks, I have been looking at those adjustments. My concern, is that if Dovecot uses a process per imap or pop connection, 2048 is not nearly enough for any significant email system.
Yes, it uses a process per each logged in user. POP3 processes are short living sho they shouldn't matter much, but yeah, if you have lots of IMAP connections that can become a problem. But typically what I've seen a single server can handle maybe 1000 simultaneous connections before running out of disk I/O. So are you sure the fd limit is the first problem you run into?
You could of course also apply Apple's multiple-connections-per- process patch posted to this list some months ago or wait for Snow Leopard which distributes Dovecot with that patch..
