I did mx query for nubiint.com and I got this result

internet address of mail.nubiint.com = 0.0.0.0

I advise you edit the MX record setting of mail.nubiint.com to point to a valid 
IP address that handles your mail.

I haven't been able to test that yet. I have been able to resolve the
error in the event logs, which was DNS related. Now I guess it's just a
matter of finding out what else could be preventing mail from coming in.

So if anyone could test this for me I'd be grateful. I've forwarded port
25 on my linksys so it should be seen as either numailsrvr.nubiint.com
or mail.nubiint.com. 
TIA

I think frustrated Admin meant to say is can you telnet FROM an external
source to your mail server name/ip address port 25?
