Bob, and all,
I'm just after a simple solution to my question, which I will re-iterate:
Can I catch incoming messages which contain file attachments with the extentions scr, exe, pif, etc using a RegEx?
Now, I assume that the answer is YES, so my next question is:
Please show me by way of an example, how to do the above as a rule.
Please, I just want to know how to test attachment filenames using rules in SA.
Regards,
Julian Milano

Yes, you could run something on a box in front of the exchange box to
filter. Many on this list have done exactly this, though I have not as yet.

If you simply want to flag all messages with attachments as spam, you
certainly don't need spamassassin. Procmail can do that just fine.
However, keep in mind that you're likely to flag NON-INFECTED messages
with attachments as spam. If your company policy allows attachments,
you're very likely to annoy a LOT of people.
I'm sure there are ways to do all of this with commercial software on
Windows working directly with Exchange, but I do not have the financial
resources to investigate. I'm limited to effective, open solutions.
