Unable to Relay 5.7.1 from another server that needs to send mail

Hello All!

I found a few questions already in the database but they were not answered completely or found another work around to fix the issue.

Here is the situation :


We have an Exchange 2007 Server (single server environment) that routes mail to a smart host provided by our ISP.  People using Outlook have no issues sending mail to external recipients.

we have a server running an application (I don't know if anyone is familiar with the product Team2 or not) that sends mail when a work order is completed.  you can send mail just fine to internal recipients but when you try to send it to an external recipient it comes back with a 5.7.1 Unable to relay.  I can telnet from the server and connect to the exchange server via port 25.  I can put in the sender ID just fine but when I put in an external email address is immediately comes back and tells me that it is unable to relay.  we need to get this working as we have tickets that our customers need status reports on.

Anyone have any suggestions?

You need to set the server that generates the email as trusted for relay - not sure on 2007, but in 2003 it would be in the ESM / server / connectors / SMTP / default / properties / relay, and add the server FQDN or IP address to allow relay.
Let me know if it works

I'm not exactly sure where to set it in 2007.  haha, that's the problem.  we just migrated to 2007 from 2003 and it was working fine because I did just what you stated.  anyone know how to do that in 2007?  I assume you'll have to use CLI to do it?

RobinHuman,

while that is a good source of information it appears to reference a piece of software that you must purchase.  Are you saying that the only way to relay mail from one server to another is to buy this software?
