Thanks,

But I believe fail2ban uses iptables, and I don't run a local firewall 
on the server. I'd prefer not to use a separate server to inject 
firewall rules on the border firewall. I might be wrong about fail2ban, 
though.

I was hoping there was a file for pop and imap in dovecot similar to the 
smtp "access" file in sendmail (which is what I use, BTW)
