OK on your thoughts, and also what will happen to mail being rejected.
One thing you did mention that made me take notice is the spamassassin
stuff.

I have to look at this.  I have only heard about it, so I will take a look
to see what this offers.  I am sure it will be a good place for more
information on the spam stuff..

Thanks agian..

No problem.  I can't claim to be a complete expert or anything.

The thing you maybe don't know is that the mail transfer agents
(MTAs) like sendmail and postfix in the Internet attempt to not
lose email.  So if you "refuse" it a notification is sent back to
the sender letting them know the email didn't get through.

Spammers do one of two things for sender.  They either use a
made up invalid address or they use a random address from their
database of email addresses.

So by refusing email you don't recognize you're causing more,
probably useless, traffic.

The best thing to do with spam is to delete it.

I recommend you look into the SpamAssassin program or one of the
other "Bayesian" filters.  These learn what YOU think is spam
over time.  They're very effective even though the spammers are
doing all sorts of interesting tricks to slip past 'em.  Hit
google up for "bayesian email filter" and you'll probably get a
good selection.  SpamAssassin is at www.spamassassin.org
