Is there a way using dovecot facilities to block an IP from

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.
