I'm going crazy troubleshooting a weird issue.
I'm running a LAMP installation using CentOS. My domain has a MX record pointing to another mail server which i rent from my ISP.
All mails sent via sendmail from my domain to external accounts works fine. Receiving mails on
email@mydomain.com from external accounts works fine.
Sending email to
email@mydomain.com from mydomain.com does ONLY work for root user not for apache user.
Here is how i've tested:
ROOT User
command '/usr/sbin/sendmail -v
email@mydomain.com < message.txt'
produces
Code:

No errors in /var/log/messages and in both cases the message is queued and accepted for delivery according to the maillog.
The email sent when run by root is present in my inbox, the one sent from apache is not. If i send from apache user to an external account (say hotmail.com) it works fine.
Any ideas ?
Thanks in advance.
