Hi Guys
I'm getting an issue receiving email from yahoo.com.au (yup good old yahoo!) from one user.
Luckily we have the NDR report which says: Sorry, we were unable to deliver your message to the following address. user@domain2.com - No MX or A records for domain2.com.
The Exchange server has 9x accepted domains. Domain1.com is the primary and used for the mail.domain.com primary mx records and the ssl cert. Domain1.com mx records point to the IP of the Exchange server.
Domain2.com (the one that's getting the problem), it's mx records point to domain1.com at the domain host.
When I do a whois for domain2.com the mx records show as mail.domain1.com with a priority of 10.
Do you think this is an issue with the domain host or do I have a configuration issue here?
Kind Regards
Aaron
