A lot of “bots” try very simple passwords say less than X characters; over and over and over again before they give up.
I realize Dovecot mitigates this by slowing them down; but always nice to have another optional layer of defense to clip this kind of garbage closer to the door.
Check out fail2ban. It's very useful for that sort of repeated bot attack.
