Postfix force sender ("From:" field)

+Yan · 01-15-2009, 07:23 AM

Hello,
We have Linux post server with Postfix running on it and 5 domains.
Everything is working fine, except one thing. I was wondering how can I force user X to be able to send email ONLY as X@domain1.com, but NOT as X@domain2.com for example. I.e. how can I create map user --> email, and force every user to be verified against this table.

Thank you in advance.

Check out smtpd_sender_login_maps and reject_sender_login_mismatch. Those enforce envelope sender.
