Rich,
ARIN is the regional registrar for IP addresses and ASNs, etc for North America. They have a WHOIS right on their homepage. The IP address you say si problematic is the Holiday Inn in Yuma, AZ. Coincidentally, I have stayed there once.

http://ws.arin.net/whois/?queryinput=!%20NET-12-105-234-128-1

If you do not get any satisfaction there, you can try talking to ATT. Since the whole 12.0.0.0/8 network is theirs. The Holiday Inn has just been reallocated the small /27 of IP addresses. I don't think you will get *too* far with ATT, but it's something. The hotel is either hacked, infected or some guest or neighbor of the hotel is using their wireless to be a pain in the arse.

...and I really dont' understand what you mean by you are being blocked from forewarding by your registrar. Are they hosting your mail too ? Are they your SMTP server or something ? I don't get it.

Quoting "Richard W. Ernst" <[EMAIL PROTECTED]>:

Our work email is being blocked from forwarding by my domain registrar,
godaddy.  they say 12.105.234.130 is problematic, so they're blocking
the whole dang class C subnet.  We, of course, own/utilize the subnet
from 12.105.234.192-255, not 130 and don't use 130 for anything.

How can I show them that they're idiots and should stop blocking OUR subnet?

Thanks,

Rich
