Mail Delivery Failure :(

[MH-Dennis]

Hello,

I have the latest versions of both cPanel and WHM on my server. All of the sudden Exim stopped working. It is receiving e-mails properly but not able to send them out. Here is an example e-mail:

------ This is a copy of the message, including all the headers. ------

Return-path: <test@server.org>
Received: from [127.0.0.1] (helo=localhost)

This is trying to send out to the Gmail servers btw.

Here is my etc/resolv.conf

domain server.org
search server.org
nameserver IP of server.org
nameserver IP of ns2.server.org
nameserver IP of ns3.server.org
nameserver IP of ns4.server.org

Any ideas? Using Exim 4.68 on CentOS Enterprise 4.5

That's it.

Check to make sure that admin@forwarder.com exists and is accepting mail directly (without a forward).

Without the forwarder address it does accept mail. Example: It directs to a Gmail account. I send mail directly to the name@gmail.com and it works. However, sending to admin@forwarder.com does not work. I can try to send to name@gmail.com from the test@server.org account but it still does not work.

I will diagram a brief overview of what has been covered:

name@gmail.com ---> name@gmail.com Success
name@gmail.com ---> test@server.org Success
name@gmail.com ---> admin@forwarder.com Failure
test@server.org ---> name@gmail.com Failure
test@server.org ---> admin@forwarder.com Failure

and yes, admin@forwarder.com does exist.

EDIT: Seems only a problem with Gmail servers.

Well, to be honest, I don't think I have any more suggestoins - although I believe I could figure out the problem with access. If you get desperate enough and are unable to figure it out, feel free to PM me. I know, most people are skeptical of providing access to their machines. But it's your call. I'm around if you'd like me to look. Without knowing the 'real' domains it's pretty difficult. If you at least want to PM me the 'real' domains I"ll try to assist you.

Well I'm thinking it's a problem with connecting to Gmail's DNS for whatever reason. But when I do 'host -t a gmail.com' it works fine.
