Can't Receive Email on Secondary Domain

Posted on 2011-03-07

We are having issues with receiving emails on our secondary domains.  The only way that we can receive the emails is to allow our server to be an open relay, and I know that I don't want that.

Did it always work or is this an additional SMTP domain?

It always worked.  But the guy before me did something and the server is an opened relay.  So I am trying to close the relay and get the domains the ability to be delivered.

If the previous article does not illustrate your needs to add the secondary SMTP domain into the RUS.  Try this page from technet.

Unfortunately I have no idea what the other person may have configured.  Your best bet is to run a few telnets in between your configurations.  The technet article should help most as it illustrates what you need.

Please have a read of the following link to resolve your open relay and when that is done, check on

Once the relaying is resolved, we can move on to the mail-flow issue.

I made teh necessary changes and now I am no longer a mail relay.  But I no longer can receive email at the secondary domains.

Delivery to the following recipient failed permanently:

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 Unable to relay for (state 14).

Okay - please check your Recipient Policies to see if the secondary domain name is an accepted domain and that the server is authoritative for the domain.

For info on where to check (in case you are not sure):

After I reapplied the policy mail began to flow again.

Very strange

Very peculiar - but glad mail is flowing again - I will hide the domain name to protect the innocent!

Thanks for the points.
