Marvin, It makes no difference and I don't think this has anything thing to do with your problem of not being able to receive mail, the MX record used by other people is hosted on an EXTERNAL DNS server, have you contacted Bellsouth to see if they block incoming port 25 on their routers.

I've got 2 host records created in my internal DNS; one for the server's Netbios name and the other for "mail", or mail.nubiint.com. I currently have MX records created for each of these. Now I'm sure this is NOT the way to do this, so my question is which MX record do I keep?
