You should be careful! Don't forget that SA is not perfect! I have received
mail marked as SPAM, but it WASN'T! If you do this thing you may lose email
that you WANT. I think a better solution is to accept those messages and put
them somplace temporarily, kind of like hotmail does. Have a folder called
SPAM or BULKMAIL for each user and have tagged SPAM moved into that folder.
I do that, and have a CRON job that runs tmpwatch on those folders and
removes everything older than X days... I don't like receiving SPAM, but I
HATE to miss a desired message!

I also check the SPAM messages regularly at the command-prompt to see how
they're changing over time, and how they're scored with SA. It's interesting
to see what these bastards are doing to get the message into our INBOX. They
send messages to me AS me, or they insert fake HTML tags randomly throughout
the message to break up words and avoid pattern searches, etc.

There is something that I saw recently that looked very interesting, and I
LOST THE LINK. It involves DNS MX-type records. When receiving an SMTP
connection, your MTA is given the sender ([EMAIL PROTECTED]). If the
special MX record in the DNS lookup of the senders domain (yahoo.com)
doesn't match the actual MTA sending the email, the connection is dropped.
Or something like that. I never got the chance to check it out! Since yahoo
lists hosts 10.10.10.1-10.10.10.20 (example) as their MX hosts, then if the
message you're currently receiving from [EMAIL PROTECTED] is coming from
HELO booger.de (10.20.30.40), then you know it's BOGUS, and the connection
is dropped. Has anyone heard of this? If so, please post a LINK!!
