SMTP Virtual Server FQDN

In resolving a delivery error we encounter from time to time, it was suggested that I change the FQDN of our exchange 2003 server in the advanced delivery properties of the SMTP server.  

The genius who configured the exchange server (not me) named it mail.domain.com (internal) and had the external dns (mx) listed as mail.domainresource.org (the doman name we own externally).  

I had the external changed to something a bit less obvious.  domainexch01.domainresource.org and things are still working fine.  

My question is, in the advanced properties do I want to enter the external dns name?  Or can I add a more generic internal DNS entry into this space.  

And what is a Masquerade Domain.  

Thanks in advance.
