We need to send mails from our domain (assume this is example.com) to our self. Now, the 'incoming' mails are handled by another server (from Google). We can send mails through sendmail to external e-mail addresses, but when we tried to send to ourselves, nothing happens! What can we do to enable this feature?
We are running CentOS with Sendmail/Apache2/PHP, mails are sent by PHP.
Try mail hosted at Google, web server elsewhere
