Reply Email going to zz0.com

[Dave]

OK I am hosting this guy and designed his site.. He wanted a mailbox for folks to contact him so I set one up.. greg (at) mudvilleproject.com

You can email him there and he replies.. BUT when I recieve his email it says it is from:
Mudville (at) cpanel32.zzo.com (the bline nameserver)

I'm sure this is a simple solution. I just didn't want to submit a ticket unless I had to.. Which I'm sure it's no big deal just something I have overlooked.. None of my other domains have this situation..

Any ideas?

I think this would be solved by a TT, since it seems like a server setting problem.

This generally would not be a server issue. How are the e-mails being sent? The FROM address is likely not set correctly or you are not logged into the correct account.

Hmmm I dunno.. I know he uses Squirrel Mail to check his mail and stuff.. I don't think he is using an email client..
It says the mail is from his greg at domain.com.. And when I tried to reply it was the same thing..

Confused....

I have a little more info now but have decided to submit a ticket because I'm afraid pasting the info here may be some weird security risk...

Ya know?
