Return-Path: <root@fedoralinux20-test>

My PHP website hosts on Apache server. Seem like it send out using user apache@mydomain.com. However, the apache user is not included in the php code. Any idea where will this user "apache" been setup ?

apache is the user under whose credentials httpd/apache web service runs.
you need to configure your php.ini mail to use the -f command with sendmail to set the email sender.
depending on how you are setting the message header in the PHP code, there is a way to identify who the sender should be .....
sendmail_path = /usr/sbin/sendmail -t -fsenderemail_address -oi

by default sendmail in the absence of the -f sendmail uses the logon as the username portion and its own hostname as the domain....
note the above will send all outgoing messages from your server using that sender....
