[FFML] [ADMIN] Changes on the mail server

Heya!

Just poking in here to let you guys kn ow that I've made a change to the 
way the mail server accepts incoming mail.  Basically, if you can speak 
SMTP, it's fake HELO messages.

To explain, something I've noticed is that a lot of spam is coming from 
bots that are faking the identification that they pass to my server. 
(That's the HELO statement - in this regard, the statement to my server 
looks like "HELO domain-name.com", at which my server responds 
accordingly.)  So by telling my server by some odd complex recipe that 
this should just be rejected, that should slow down the spam.  Those of us 
on the admins list will hopefully see a decrease likewise.

Also, I'm now using a realtime black list (RBL) - which I'm keeping an eye 
on, just to make sure that I'm not killing legitimate email.

So this said, if you get something that says it was returned to you by the 
server AND YOU SENT IT, please contact me.  There are alternate ways to 
get me (dennisthetiger 4t gmail.com is a good one in a pinch) that will 
work around the server.

-Dennis
