Hi, my webapp send mail over iRedmail server(with authenticated account: eg: webapp1@mydomain1.com), but i can't send mail with custom header like:
Return-Path: bounce-webapp1@mydomain2.com
The reason behinds is: i have another mail server @mydomain2.com to processing bounce-email (detect spam sender, detect not-exist recipient address, v.v...)
How I can configure iRedmail(postfix) to allow webapp1@mydomain1.com set a different "Return-Path" header like:
bounce-webapp1@mydomain2.com
(when i set custom header & send, i see error in postfix log, like that:
Sep 17 10:55:06 mail postfix/smtpd[28996]: NOQUEUE: reject: RCPT from unknown[113.x.y.z]: 553 5.7.1 <bounce-webapp1@mydomain2.com>: Sender address rejected: not owned by user webapp1@mydomain1.com; from=<bounce-webapp1@mydomain2.com> to=<abcd@xyz.com> proto=ESMTP helo=<mydomain1.com>
Thank you very much!
