Hi Brad, You'll need to make the ISA firewall an inbound SMTP relay for your Exchange Server. HTH, Tom www.isaserver.org/shinder Get the book!

Mitchell [mailto:bmitchell@xxxxxxxxxx] Sent: Sunday, August 22, 2004 1:30 PM To: [ISAserver.org Discussion List] Subject: [isalist] Setting Up GFI Mail Security on the ISA Gateway http://www.ISAserver.org I have the ample amount of time to learn ISA before having to manage it, unlike I am sure most of you. I have several machines running and on my ISA box I want to install GFI Mail Security (Gateway). I have exchange 2003 up and running on a separate machine and have the mail flowing. What publishing rules do I need to have in place before GFI is enabled? Will it be like exchange as it is a mail server?
