Yes, that sounds about right.   In the file db.mms (for the mms. zone)  
you would insert an A record for the origin, not for a host called mms  
(which would end up being mms.mms.)  So, if the IP address for  
mms.ora.com is 192.0.2.1, your zone file for mms. would look something  
like this:

---
mms. IN SOA name.server.ora.com. admin.name.server.ora.com. (
      2008081812
      30m
      15m
      7d
      1h )

      IN NS name.server.ora.com.
      IN A 192.0.2.1
---

Good luck,
