Create a Subdomain for an Exchange Alias

I have a customer who requested if they can have a different 'alias' for their Email Address.  Example would be our domain is called "xmen.com" and they would like their email address to either be "xfactor.com" or "xfactor.xmen.com".

The environment is Windows Enterprise Server 2003 Domain hosting Exchange 2003 Services.  We have BIND as our 'authoriative' DNS with AD DNS as a backup.

Internally we can add any alias's we want and users can send/receive email.  The issue we have is when they send email outside our domain as we receive kickbacks from emails unable to send.

We want to ensure that when the users send email from their accounts the distant end sees their email address as "xfactor.xmen.com" and not "xmen.com".  There is not a registered namespace for "xfactor.xmen.com" only "xmen.com".  Is there anyway we are able to set up DNS and Exchange appropriate to meet this requirement without creating a whole new domain and a registered namespace?  Thanks.

You have to register xfactor.com and point it (A or CNAME record) at your exchange server.

For xfactor.xmen.com (assuming you already own xmen.com) you have to enter the domain name into your public facing DNS and point it to your echange server (again, with wiother an A or CNAME record).

Are you explaining that 'xfactor.com' needs to be registered at the '.com' level?
We don't have the option of registering either namespaces.  When we pointed xfactor.xmen.com to our Exchange server we still received errors.  Perhaps we did not set it up correctly but whatever advice recommendations you all can provide would be most helpful.  Thanks.

If you want the email addresses to be @xfactor.com, then you will have to register that domain.

How and where did you point xfactor.xmen.com to your exchange server?  It must be either an A or CNAME record in your public DNS server (viewable from the internet).
