ISAserver.org - RealTime Article Update Hi ISAlist, Title: Configuring an Inbound and Outbound SMTP Relay to Complement ISA 2004 Firewall Protection for Exchange Servers Author: Thomas Shinder Summary: I?m a big proponent of the SMTP relay concept. A properly configured SMTP relay can protect your Exchange Server by preventing untrusted SMTP servers on the Internet from directly communicating with your Exchange server. An SMTP relay doesn?t require a significant amount of system resources and you can install the IIS SMTP service without incurring the resource or security overhead you would have if you installed the IIS W3SVC (World Wide Web service).In this article we'll go over some of the important details you need to consider before rolling out an SMTP relay to complement your ISA 2004 firewall e-mail protection design.
