Exchange 2010 cannot send to specific domain
Posted on 2013-11-04
We cannot send messages to a single domain. (blueblanket.com)
When I run nslookup for the domain I get the following output.
We are getting an incorrect mx record ip address returned. I called the remote host IT staff and they said the mx record ip address for remote host mail.blueblanket.com should be:
The it staff at the remote host do not recognize fe.mail.blueblanket.com and they say it is invalid. Flushing the caches on both the domain controller and the exchange 2010 server are ineffective.
What is the best course of action to resolve this. The rest of outbound mail is good. I was thinking of creating a custom send connector for this domain but wanted to check first. Seems like a dns glitch. Our mail server is configured to use external dns.
Default Server: our local domain controller.com
> set type=mx
Server: our local domain controller.com
blueblanket.com MX preference = 10, mail exchanger = mail.blueblanket.com
blueblanket.com MX preference = 20, mail exchanger = fe.mail.megapathdsl.net
fe.mail.megapathdsl.net internet address = 126.96.36.199
