Emails from Google / Hotmail being rejected, help please!

[MrPresident]

At the end of last week I reinstalled one of our servers with WHM/cPanel and as far as I knew, it was setup correctly.

However, I have found that anyone trying to send me emails from a Google or Hotmail account are instantly receiving notification of mail rejected with the following error:

Delivery to the following recipient failed permanently:

David@iStarvin.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unrouteable address (state 14).

The domain is using the servers configured nameservers so should be working correctly and I've checked with a lookup site and the MX records point to the server IP correctly.

Just to point out that I can receive email from any other source, just not Google or Hotmail.

I've looked on these cpanel forums and Googled with no luck so any help in resolving this issue would be appreciated, thanks.

I'd look at several things....

first, use a number of DNS checking sites to verify all is well there. When I'm looking, I usually check with at least a half-dozen to make sure all are seeing and reporting the same things.

What, if any, blacklists, sender verifications, etc. are in use?

Did you check your own mailserver logs? According to Google it was actively rejected by your mailserver. So there should be an entry.

Try using this command to check the email in exim's log for CentOS and RedHat systems:

exigrep user@domain.com /var/log/exim_mainlog

If your machine is FreeBSD, it would be this command:

exigrep user@domain.com /var/log/exim/mainlog

You would replace user@domain.com with the email address recipient, the one that was rejected.

Next, I'd suggest trying this command for that same email address:

exim -bt user@domain.com

This will show if the email address properly routes on your machine or not (it should route locally if that email address is on the machine and properly setup.

Gmail and hotmail accounts are sending to his machine and the accounts on his machine aren't receiving the emails (the emails are bouncing back to gmail and hotmail). He isn't getting bounces when sending to gmail and hotmail, so it isn't likely a blacklisting issue here for his IP, since it's gmail and hotmail unable to send to his server. It sounds more like a local delivery issue.
