Allow postfix  to send email with different sender from SMTP account... Error: 

postfix/smtpd[27402]: NOQUEUE: reject: RCPT from unknown[125.123.123.100]: 553 5.7.1 <user@xxx.co.nz>: Sender address rejected: not owned by user user@xxx.co.nz; from=<xxx@xxx.co.nz> to=<xxx@gmail.com> proto=ESMTP helo=<localhost>
Edit postfix configuration: 
[root@mail ~]# nano /etc/postfix/main.cf
Change from: 
smtpd_sender_restrictions = permit_mynetworks, reject_sender_login_mismatch, permit_sasl_authenticated
To: 
smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated
Then restart postfix... 
[root@mail ~]# postfix stop
postfix/postfix-script: stopping the Postfix mail system
postfix/postfix-script: waiting for the Postfix mail system to terminate
[root@mail ~]# postfix start
postfix/postfix-script: starting the Postfix mail system
[root@mail ~]#
That's it.. You can now change your from or reply-to in your PHPMailer. :) Hope this helps...
