Hi Marvin, Disable all the other SMTP rules you have in place, and remove any SMTP related packet filters you have, unless you're using the packet filter approach to publishing the SMTP server. Make sure that socket pooling is disabled for the SMTP service too. Also, make sure the SMTP service is listening on the Internal interface of the ISA firewall. Not "all IP addresses".

I configure this rule with the following settings: IP Address of internal interface of the ISA server. IP on external interface of ISA server that handles mail. Apply rule to SMTP server Apply rule to Any request I notice that there is already a Mail wizard rule in place, but it lists the IP of the internal mail server and not the internal interface of the ISA server. I've followed the steps as outlined in part 1 of this article so what could I be missing here?
