First thanks in advance.
OK, I have two email domains. I'll call them texas.org and texas1.com. The primary domain is texas.org and mail flows normal using that. I setup an alternate accepted domain under organization-> hub transport for texas1.com as authoritive. I've setup with our domain registrar the A record and the MX record to point to the correct IP address which is also the IP address of the primary email (texas.org). When I do a test using DNS-Stuff.com I get a report that is saying there isn't an MX record. When I do a smtp test telneting to the domain name using the texas1.com it connects but when doing an ELHO it returns the texas.org name. I'm in the final stages of migrating from exhange 2003 to 2010 and everything is migrated over and I'm fixing to remove the 2k3 box. Could that have an impact?
What am I missing.
