You should already have a new zone in your DNS of your companyname.com, in that zone add the MX, leave the child blank and make the FQDN of the mail server "mail.companyname.com", then add a Host (A) record to the zone of Mail {ip of your mail server} no PTR.

In SMTP on Exchange click the Delivery Tab, in the FQDN field put the mail.compayname.com and click "check DNS" it should resolve without any problems. You may also want to make sure your IP reverse lookups.

Even though our domain here is .local when you look at our SMTP is says "mail.company.com", and resolves fine.

Subject: [ExchangeList] SMTP server FQDN

KB article 843106 says
6.       Verify that value that is listed in the Fully-qualified domain name box is the actual FQDN of the server.
I am unsure if this actual FQDN should be the local name or the name that the server is advertised as in the MX record for the external domain.

If we have a local domain (mydomain.local) with a exchange server named mailserver and a external domain (ourcompany.com) and that external domain lists the MX record as mail.ourcompany.com.

The internal FQDN for this server is mailserver.mydomain.local and the external FQDN for the server is mail.ourcompany.com.  Which name should be put in the SMPT server dialog box?

I found this on the Experts Exchange web site and it seems to say that one should use the local FQDN and not the internet FQDN. This seems to be a different suggestion than what people said on this list earlier this month.
We have an internal and an external domain, with internal and external IP addresses. My e-mail recipients see my internal domain name and my internal IP address for my mail server, which cannot be resolved by DNS to my public domain of blueridgepro.com.

How do I set my Microsoft Exchange Server box so the outside world sees my public IP address and domain name, but not my internal data?

This question posed on 01 April 2006
You could change the fully qualified domain name (FQDN) sent by Exchange Server from SMTP Virtual Server properties to match the public FQDN, but it isn't recommended and it isn't a complete solution -- the Message-ID will continue to have the actual FQDN.

Exchange Server does not have any native tools to rewrite SMTP headers. You may have to look into third-party tools like MailSweeper that do this, or code something yourself to run on your SMTP gateway
