Hi,
Currently have the following setting in main.cf but I do not know how
to create an exception. Because there are some authenticated users
that should not be rejected by
reject_authenticated_sender_login_mismatch.
I'm a noobie to postfix myself but I'll have an educated guess and say
'reject_authenticated_sender_login_mismatch' will REJECT if sender does
not match the sasl_username without any exception. If you want to allow
an sasl_username to send messages for an non matching sender, then I'm
pretty sure you will have to remove it from the smtpd_sender_restrictions.
If you only want to grant certain users permission to do this, you could
write a script and run it as an external policy in place of that
restriction. Postfix will pass the sasl_username and sender details over
to your script, which could then veto each request based on the
sasl_username. Do you know how to do this? If you don't, I could post a
simple PERL example tomorrow.
Mick.
