Exchange 2007: 501 5.1.3 Invalid address Short Name Rcpt SMTP address

Summary: Application servers relaying through Exchange get NDR 501 5.1.3 Invalid address

When viewing the SMTP logs on the Exchange server or packet captures you see the short name being used instead of the fually qualified SMTP address.

mail from: applicationserver@company.com
rcpt to: user
invalid

Should be rcpt to: user@company.com

Servers should be specifying the fully qualified SMTP address, however it may not. Some applications such as scanners, listservs communigate pro.

Resolution: Set the defaultdomain parameter on the receive connector.

set-receiveconnector "nameofconnector) -defaultdomain company.com

This will append the domain when applications use the shortname rather than the fully qualified SMTP address.

This was the exact problem I ran into. Just migrated from an exchange 2003 to exchange 2010, and ran into the pitfall of our old reporting server no longer sending emails out.

Your command did the trick, though you need to clean up the syntax a bit.
