EXE Files Slipping Through

But those are so easily caught by SpamAssassin!

Which is what I resorted to doing.

Subject: EXE Files Slipping Through

Im hoping someone can help me here.

By using filename and filetype exceptions I've allowed myself to send
and receive .exe files. I've banned this for all other addresses though.
The reason for this is that it catches a huge amount of malware that
slips through Clamav/Sophos - at the moment its hundreds of "Fedex
tracking number" emails with a zipped exe attachment that aren't being
detected!

My problem is when malware emails arrive which are addressed to me AS
WELL as other people - This means the infected email is actually
delivered to the other people on the email! Is this normal behaviour?
I'm smart enough not to open these emails, but other people are not!

Is there any way to stop this behaviour without me losing my ability to
send/receive EXE files?

Cheers!
