Unable to relay for subdomain

I have a subdomain called fac.jmls.edu hosted at live@edu. It receives email fine from outside and sends mails fine to everybody. Whenever an email is send internally, it generates 550.5.7.1 unable to relay for user@fac.jmls.edu.
I have front end SMTP server and I have defined that server in relay settings and also this domain is set up as an accepted domain on Exchange 2007 servers.

Parent server(jmls.edu) is running on Exchange 2007 SP1 while subdomain is fac.jmls.edu whose email accounts are created at live@edu. There is only one AD domain called jmls.edu.
is fac.jmls.edu hosted on the same 2007 server or on a different server?

There are just AD accounts for fac.jmls.edu and no mailboxes hosted internally.
How are u sending emails to them if there are no mailboxes??

Contacts has been created for user@fac.jmls.edu internally and mails are sent through the contacts. The mailboxes are hosted at live@edu. These mailboxes received mails fine from outside but having problems in receiving mails from jmls.edu clients.
It isn't clear which domain you have in the accepted domains list. Is the subdomain listed?

I have all the domains (jmls.edu, fac.jmls.edu) listed as an accepted domain.
remove fac.jmls.edu from accepted domain and restart transport service.

I added fac.jmls.edu this morning only though I created the domain last week. I think it is related to more of MX record internally. I havent created the MX record for fac.jmls.edu so far. Its not giving me an option to create that.
donot create MX internally
Rather remove that domain from accepted domain.
If a domain is listed in the accepted domain list, then that tells Exchange it is responsible for email for that domain. If the email boxes for that domain are elsewhere then it needs to be removed from the accepted domain list.

Do you have users on your Exchange server that need to send email out as that sub domain?

As i mentioned previousely, I added fac.jmls.edu this morning only and I am having problems in sending emails (internally) to fac.jmls.edu since last weekend. But I am going to delete that fac.jmls.edu accpeted domain entry and will restart the transport service this evening. Lets see how it goes.
okies.

Restarted the Transport services after removing fac.jmls.edu as an accepted domain. Also i noticed that fac.jmls.edu cannot send/receives emails from inside (jmls.edu parent domain)..
