Chris,  

Methinks the router would be the best place, but we don't control our router
(the ISP does).  So far I have 84 rules on my SW Pro, 73 are DENY SMTP,
there is a limit - not sure how many.

I can't seem to block ALL traffic from the bad guys due to the SW
re-ordering the rules.  If I DENY DEFAULT from x.y.0.0 - x.y.255.255 to *,
it puts this rule below the ALLOW SMTP from WAN to DMZ <mailserveraddr>
(which is required due to our email server).  If I DENY SMTP from WAN
x.y.0.0 - x.y.255.255 to DMZ <mailserveraddr>, it puts this rule on top.  In
short, the more specific the rule, the higher it goes in the list.  FYI - I
tried all kinds of rules to get the deny's on top - no joy.

I did setup a "bait" mailbox by the name of John@ and have gotten 5 spam
emails in 4 days - I then look at the inet headers and add the smtp server
that it came from.  My SW log shows a dropped smtp every 5 minutes or more,
almost all from the Chinese/Korean list.

servers

                Should this be done in the router or the SW?  There is only
so many rules 
                in the SW unless I'm doing something wrong  ;)
