I have Exchange svr 2003 on Win Svr 2003.  When mail is sent out from exchange the headers show my exchange svr IP , but the server name is what I called my Active Directory computer name (server.local.com)  Of course I cannot change the whole name of my server to its real internet name, but can I modify some host file just to fix this problem.  The Real internet name should be mail.company.com

ESM, Servers, <your server>, Protocols, SMTP. Right click on the Default SMTP VS and choose Properties. Click on the tab Delivery and then Advanced. Change the entry in FQDN. Don't bother with check dns as it will not probably not work.

I changed the DNS name but the header on the recieved email is still showing the AD name.  Should I wait, or restart Exchange?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I read and implemented the changes carefully.  The server still calls itself server.gg.com which is the AD name.  Do I need to modify some other part of the OS?

As long as you have put it in the FQDN box, not the masquerade domain, then it should be fine.
The only other thing I can think of is that something else is interfering with the SMTP traffic. Is there anything else on the server? AV/Antispam for example?

Look through that application to see if there are any settings in that toll that could be changing the SMTP header.
