Anyone hear of some sort of a cracking method that uses cgi-bin/formmail?
I've seen alot of these in my httpd/access_log files
lately. I don't have formmail.pl anywhere on my system - I flushed all of
the cgi-bin stuff that came with apache a long time ago.

Spammers are actively looking for such scripts to abuse to send junk mail.
See, for example, http://securitytracker.com/alerts/2001/Mar/1001108.html
