**So, my question is:

• 1) Why i have recived and delivered have the same values (approx)?
• 2) How can I check if an email has been delivered?
• 3) How to change default "root" and "www-data" user (FROM / RETURN PATH) to another? I have changed this in script, but postfix ignore scripting values and send every mail from root (we have .php send cron's in /etc/crontab)

• 4) WHY APPROX 100 % MAILS RECIVED HAS BEEN ADRESED TO MY SENDER HOST? Host/Domain Summary: Messages

  Received Waiting for respond, Regards TB**
