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.
