Peter,
try running something like McAfee Spamkiller before your mail
program eg Outlook.
that way you can kill them before "accepting"
them.
This will stop giving away you have a valid email address for them to
pass around ie onsell.
You can then set filters to block future traffic
from those sources.
This way you also remove the need to download the
spam and can kill it at the ISP.
That should slow it down
also get
your ISP/mailserver to automatically reject all emails sent to addresses that
are not valid.
you might lose a
few you want but anybody sending good mail to you should know your address
anyway.
It will blow away all
blanket spam emails though.

When you are the MX for the domain you have no choice
but to accept
at least the headers.
Good header checking, with
manually added rules in the case of an
outbreak, should reject at least
half of all spam and virus infected
email. Pass the rest (excepting
your optional whitelist) to
Spamassassin or similar, then onto a
trained spam filter on the email
client.
Not a lot gets through
that.
Be careful with RBLs - there are many falsely accused and they
don't
stop new
spam.
Peter.
