MX points to different sub-domain than Exchange receive connector - it works - why?
Posted on 2012-04-11
This may be a silly question, but I want to know why my setup works when a hint of some perhaps common sense tells me it probably shouldn't.
Setup is SBS 2011 with Exchange where my domain and website is hosted externally.
My MX records point to mail.mydomain.com. I have an A record that points mail.mydomain.com to my ip of my server.
That all seems fine and I guess that's all it needs to work, but my receive connectors in exchange on the first tab that says "Specify the FQDN this connector will provide in response to HELO or EHLO:" is remote.mydomain.com.
I assume that last bit should be mail.mydomain.com, but what will changing it do for me? More, less or nothing?
Many thanks, Warren
