mail / hostname mixup

Trying to make FrontPage created forms work .

When I try to send forms to my clients' new BellSouth address it bounces for this reason…

myemail@bellsouth.net

SMTP error from remote mail server after MAIL FROM:<tannerst@server.domain.com> SIZE=2249:

host mx00.mail.bellsouth.net [205.152.59.32]: 553 server.domain.com does not exist

When I try to send these forms to myself at my RoadRunner address they bounce for the same reason.

myemail@nc.rr.com

SMTP error from remote mail server after MAIL FROM:<tannerst@server.domain.com> SIZE=1853:

host ncmx03.mgw.rr.com [24.25.4.97]: 553 5.1.8 <tannerst@server.domain.com>… Domain of sender address tannerst@server.domain.com does not exist

Another example:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

artf@domain.net

SMTP error from remote mail server after RCPT

What could cause this?

My info:

cpanel 10.x

smtp port 25

exim 4.5x

ran:

/scripts/rebuildnamedconf

/scripts/fixndc

service named restart

DNS zone for hostname is already there also

I think this might be causing the problem

I have mydomain.com on server #1 (also host domain)

It is my business domain as well, which I moved to a dedicated server of its own but had to keep the dns zone on server #2

Now I got this going:

server #1 holding mydomain.com dns info and server.mydomain.com hostname

server #2 hostanme is server2.mydomain.com

server #3 server3.hostname.com

Each time I login to #2 and #3 I got the popup window "A entry for hostname not found". I ALWAYS add it and it pops up again later on. I ran /scripts/fixndc and its already fixed.

How can I prevent this? Its basically saying hostname not found. Its not acknowledging when I add the A entry.

Any ideas?
