Milter-Greylist installed/configured.

   As an additional method to reduce SPAM I have installed the 
milter-greylist onto the main mail server (mail.flora.ca).


" Grey listing works by assuming that, unlike legitimate MTA, spam 
engines will not retry sending their junk mail on a temporary error. The 
filter will always reject mail temporarily on a first attempt, then 
accept it after some time has elapsed.

If spammers ever try to resend rejected messages, we can assume they 
will not stay idle between the two sends (if they do, the spam problem 
would just be solved). Odds are good that the spammer will send a mail 
to a honey pot address and get blacklisted in several real-time 
distributed black lists before the second attempt. "

Mail from an unknown source will be delayed a bit because of this, but 
if it manages to reduce SPAM it will be worth it.   If you have an email 
address here and you wish me to disable this feature for your address, 
please let me know.
