Thank-you very much that helps. Regards, Shawn -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, November 09, 2001 11:11 AM To: MS-Exchange Admin Issues Subject: RE: Exchange SMTP Routing
We are running Exch 5.5 sp4 on a mix of 2k sp1 and nt4 sp6. We have a couple of dual processor nt4 sp6 boxes in the DMZ with port 25 from outside open to them only. These servers have Trend InterScan Virus Wall and Trend InterScan E-Manager for Virus protection and content/attachment filtering. They relay all inbound email to our Exchange Org only after it has been scanned and content has been checked. We find it works very well for us. The virus walls is configurable to process only email destined for domains that we specify as well as to allow outbound email originating internally only from clients that we specify. We find it a very workable and highly configurable solution.

We are looking at building a server that just does SMTP relay\filtering\scanning and put it in our DMZ. We are also looking at putting Trend virus scanning on the box so that our mail is scanned by two different AntiVirus companies before delivered to the users desktops. Our logic behind this is sometimes Trend comes out with a pattern a little quicker than Symantec, so we do both. We also do attachment filtering with Norton For Exchange. I guess I have a couple of questions about this; 1. What is everyone else using for SMTP relay. What software, location of server, etc. 2. What is the best SMTP relay software\hardware? Should I just use another install of Exchange on a regular server`? Any suggestions or relevant web sites will be greatly appreciated.
