I'm about to bring up a new mail server running Ubuntu 11.10 with Dovecot 2. I've been using 1.2 all along and there are a bunch more config files in 2. In 1.2 I just edited the protocols statement but I can't find one in version 2. Is there a way to disable pop3 or do I just firewall the ports?
In the example dovecot.conf there's a protocols setting. If you don't see any, you can just add your own wherever. "protocols=imap" should work.
And a related question, I've been using imaps on port 993 but I hear that's not the best solution anymore, I should be using imap with STARTTLS? How do I disable imaps?
Well, http://wiki2.dovecot.org/SSL explains this more. I don't think you really need to disable imaps, but if you want to, you can do it with:
service imap-login { inet_listener imaps { port = 0 } }
