I have a Windows 2003 Server installed with Exchange 2007 SP1. It has the mailbox, client access, and hub transport roles installed on this one box. There is no edge transport server in my environment. On the DefaultReceive Connector, I have checked for anonymous users so that I can receive email from users outside my organization. Currently, the FQDN on the Default Receive Connector is servername.ad.companyname.com. Should this be changed to what I have for my MX record instead? I did not think it was wise to publish the name of my Exchange server.Any insight is very much appreciated! Example for question: Company name - ACME Exchange server name - server1.ad.acme.com OWA site - email.acme.com MX record - mail.acme.com

Hi, If there's no Edge Server in front of Hub Server and the Exchange Server is facing internet, then we need to configure Internet Mail Flow Directly Through a Hub Transport Server. Besides, we need to register MX resource records for all accepted domains in a public domain name system (DNS) server. Note: Dont modify the FQDN value on the default Receive connector named Default <Server Name> that is automatically created on Hub Transport servers. If you have multiple Hub Transport servers in your Exchange organization and you change the FQDN value on the Default <Server Name> Receive connector, internal mail flow between Hub Transport servers will fail.

Great link, butit's for outbound mails. I believe the question was for inbound email. What about removing the internal server name for inbound. Receive connector. Can you make atransport ruleto achieve this?We have a case where we are sending messages to a domain andtheir spam software is doing reverseconnection using our MX and the mail is bouncing back,becauseour public server nameis different from the server name in the smtp response.
