Is there a way using dovecot facilities to block an IP from attempting POP3 connections (similar to the sendmail access file for smtp connections)? I usually do this at my border firewall, but if there's a quick and dirty way in dovecot to do this, it'd make life a little simpler.
Thanks

The reason I'm asking about all of this is that a particular IP address is attempting to connect to our pop server, and it's trying every possible common user name (I think this is call a dictionary attack).
I can't restrict access to a particular IP subnet because our users access their email from all over the place. So this suggestion seems to not be a solution, as I see it.
Thanks though.
If I have to, I'll just go put this IP on the firewall, but I don't have remote access (for security), so it's a little more effort than accessing the pop server.
