Does Dovecot have a facility to block pop3 and imap logins by IP address. I usually do this by putting the IPs in my border firewall, but it's in transition currently to a new one, and I'd like to end connection fairly fast.

You probably want to compile in tcp_wrapper support and handle it that way

You might also hook into a the post-login script if you need some bizarre logic to determine whether to allow a login or not, but this is later in the session setup rather than block-on-sight like a firewall.
