Hi Jon,
just my 5 cents,
eventually you can figure out if they are trying to login directly to you imap/pop3 ports or maybe through a webmail?
In every case why don't you give a try to a fail2ban program to block automatically login failures through iptables and of course upgrade your dovecot's installation?
