i am running Isa2000 server on win2000 machine with all current SP's.
due to inbound  email that carries viruses and worms i set up STMP filter to weed malicious extentions (like .pif .scr .exe etc') so far i did as follow:
1)  added window component SMTP service
2) Disabled SMTP service socket pooling
3) configured SMTP service to listen on the internal ISA IP address
4) created remote domain
5) configured IIS 6.0 SMTP service to relay to the remote domain (exchange 2003)
6) configured MTP oublishing rule on the ISA
7) configured SMTP filter to block certain extentions.

however emails with those extentions keep on coming to my mail server....
any ideas how to drop those emails on the ISa level?

There are programs like GFI's http://www.gfi.com/mailsecurity/  that may help also. Most Antivirus solutions for email gateways provide this function also. Trend-micro's does.

That's M$ for ya. I am sorry to hear that your machine got messed up, but it's straight from M$'s pages...
We use Trend-Micro AV on our exchange and smtp servers, it works well. I realize you want to strip the attachments on the isa level, if M$ can't tell you how to do that then I'm not sure who can.
