I've mentioned this before but only heard from one other person who has experienced this, but it's becoming a pretty serious issue.
The situation: A spammer sets a bot on a fishing attempt to gain email addresses, causing numerous login processes to spawn and suck up all available resources.

However, the underlying problem with Dovecot would remain, and so it is worth fixing that too!
