Now, there are still the more generic ways, yet probably requiring a bit more 
guesswork; for example, assuming binary lsof is available on your system:

        sudo lsof -n -i :imap,pop3

On the other hand, I don't remember exactly what happens when that 
mail_max_userip_connections limit is hit; doesn't Dovecot log some hint that 
would allow you to track the "culprit"?
