Re: No incomming mail

This is because the DNS reverse mapping maps your IP (
to r40h17.res.gatech.edu rather than greyghost.gt.ed.net. Note the

Thus we know that troll-gw.gatech.edu and gatech.edu are the
nameservers which supply authoritative reverse-mapping for
your IP address. If you want them to change that information,
you'll have to talk to the people who maintain those servers.
Here's what we get from 'whois':

So it looks like you'll need to contact Ron.Hutchins@OIT.GATECH.EDU
if you want to get your reverse-mapping changed.
