Hello Gideon12, I too am interested in what others have to say about getting your original post to work: routing all mail through an SMTP server. However, my reason is not the same as yours. I find that posts like yours help educate us about others challenges. I look forward to someone providing ways to get your original post to work. Thanks, Robert ________________________________ From: Gideon12 [mailto:gideon12@xxxxxxxxx] Sent: Mon 2/6/2006 5:13 PM To: [ExchangeList] Subject: [exchangelist] RE: Mail Routing - Making Exchange 2003 Dumber http://www.MSExchange.org/ If you fail to see a need or reason with something, you don't need to reply. While I'm more than happy to describe in detail what is being accomplished, I'm not going to justify it. I am hopeful that we are all professionals here, and will try to help each other out, not criticize each other's environment. BTW, what's the fun of just running an Exchange infrastructure?

That in itself is problematic.
