550 5.7.1 Unable to relay - 27.Aug.2004 5:58:00 PM

I recently install an Exchange Server 2003 for the first time. All is working well with inbound and outbound email for Outlook (native and Web clients) for all of my domains.

The problem I am having is that we have several application servers on our local area network which use the Exchange Server as a relay host to send email to outside addresses. In Exchange 5.5 I accomplished this simply by allowing relaying from local subnets. I cannot seem to find a similar setting in 2003.....so my applications report "550 5.7.1 Unable to relay" when trying to send email to the internet.

Can anyone point me in the right direction. Thanks.

Check the relay settings for your SMTP Virtual Server. In Exchange System Manager drill down to Servers->"your server"->Protocols->SMTP->Default SMTP Virtual Server and right-click->Properties. Add the desired addresses under Access->Relay Restrictions. That should to the trick.

Good luck! [Smile]
