Instead of blocking a symptom, fix the problem.
You need to find out why/who/how some one is sending unauthorized e-mails
out of your network/
Could this be virus activity?
Could a computer on the LAN being used as a spam relay?

Subject: [isalist] SMTP Service blocking
http://www.ISAserver.org
Hi,
I have installed Microsoft ISA 2000 server on Microsoft Windows 2000
Machine. I am able to block particular site in a particular, and able to
access pop3 mails via ISA Server. But lot of unwanted mails sent from my
system without my knowledge, I would like to block all this unwanted mails
sent out from my system. I want to allow only one SMTP IP address to be
allowed via ISA.
Can anyone help?
Thanks
