I removed 2 IP addresses from one of my recieve connectors, and ever since then, I can't receive external email.  I added the IP addresses back and even restarted the server, but still am not able to receive external email, only internal email works.  Please help.  Here's the error message I get when I send one from my gmail account.


Delivery to the following recipient failed permanently:

     xxxxx@domain.org

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 Address unknown (state 14).

In looking at the even log, I see this:

Anti-spam agents are enabled, but the list of internal SMTP servers is empty. If there are any MTAs between this server and the Internet, populate this list by using the Set-TransportConfig cmdlet in the Exchange Management Shell.

Then  for months, I see this message, but I've been getting this for months, so I don't think this is it:
There is no valid SMTP Transport Layer Security (TLS) certificate for the FQDN of elisha.amazingfacts.org. The existing certificate for that FQDN has expired. The continued use of that FQDN will cause mail flow problems. A new certificate that contains the FQDN of elisha.amazingfacts.org should be installed on this server as soon as possible. You can create a new certificate by using the New-ExchangeCertificate task.

Yes you will get event id 12014, 16, 18 for certificate related errors.

You can create a self signed as well as third party.
i will recommend to get a third party from GO-DADDY which was cheap and best than other CA..

the question is, I've installed certs on servers, but how do I install it on my exchange server for exchange, I've only installed certs for IIS.
How do I make the request, and then installing it, can you point me in the right direction.
