Sorry this is a little off subject, but your the mostly like group to
care.
I have been careful to set up Exim so I'm not an open relay, actually
Exim made that very easy thanks!
But tonight I was checking my httpd server logs and notice that some
agents have been hitting /cgi-bin/formmail.pl and running spam through
my system. I had set up formmail to only allow specified referrers to be
able to send mail, but a bug in formmail will allow anyone WITHOUT a
referrer to send mail!!!!
It is fixed now, but if you have formmail running on your httpd you
better close this hole!
