Send Email to google apps is OK but the others are failed.

Hello

This may sound strange but it's the truth.

The server is Centos 5.3 x86_64 with DA Custombuild Apache 2.2.

This domain is not using internal ip for mail. and don' use internal mail Server to handles emails (Unchecked)

When I use Joomla send a contact email with php Mail Function, the email will go successfully to any domains that are using Google Apps for mail server both hosted in the same server or outside the server.

Anyway, the same scripts can't send email to yahoo.com, hotmail.com or anyother domians which don't use Google Apps.

HELP: How I can send email to all domains not only google apps.

This domain is using Google Apps too. It is using a DNS Gateway to assign A Record to the domains and MX to mails. This doain use Mail in the server is only sending email by php never receive any email locally.

Thanks

Do you have rDNS setup for your IP?

Yes. Everything work fine as usual event sending email by DA.

Some customers domain use ns1.mydomain.com & ns2.mydomain.com as DNS Setting and use internal email both sending and receiving. They can't also sending emails to yahoo or hotmail.

If you have any idea please advice.

Thanks

All of your clients are using the same ip?

The best place to start is by looking in your exim log (/var/log/exim/mainlog) to see what happens when exim attempts to deliver to Yahoo and others. Otherwise you are just shooting in the dark.
