Exchange 2010 relay error
I'm having problems configuring relaying on Exchange 2010.
Right, I've got an intranet page written in asp .net that sends an email to a group of addresses stored in an access database. The problems start when the page tries to send emails outside of the domain, sending emails internally work fine.
The error message is:
In EMC I've made a receive connector and set the network tab to receive mail from the local machine IP as per instructions here Allow a Server to Relay Email in Exchange 2007 and 2010 | Techieshelp.com |IT Problems (funny enough this page is now blocked when it was working fine this morning). Using telnet I can send an email using SMTP commands so I can't see what the problem is :confused:
Server Error in '/' Application
Mailbox unavailable. The server response was: 5.7.1 Unable to relay
