I also agree with Bill Brock your initial post looks like a DNS resolver issue on the client side (the system you are testing from). you should debug this before assume this is a DNS issue on the server. just do a nslookup on the client to see if the DNS is returning the right IP address. Your client may be resolving the mail IP from different source (i.e. cache or local host file).
