Hi guys, I have the following question:
Is it possible to restrict some virtual accounts from sending emails
through my Postfix?
What does "through" mean ?
If you mean FROM an address that is in your virtual_*_maps, then no, not
trivially.
I mean clients connecting to my Postfix to send emails to external MTAs.
Currently only authenticated users relay emails through my MTA. What I
want to do is that only SOME of them can do so.
I have Postfix 2.3.3 running on a box with several virtual accounts. I
That's very old.
I'll see if I can upgrade
want to prevent some of them from sending emails (I just want them to
be able to receive).
How could I do this?
With a check_sender_access restriction in smtpd_recipient_restrictions.
Ok. Should it be something like this in /etc/postfix/access
someu...@domain.com REJECT
And then:
smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/access
Is that right?
Yes.
I've been reading about smtpd_client_restrictions but I don't know if
I can do a login-based restriction.
What does login have to do with it ?
BTW, I'm using Dovecot's SASL authentication.
That's not directly related to what you asked.
Ok, I just posted the info in case something might be done from
Dovecot's side to handle users' permissions or something.
Dovecot plays no part in mail transportation.
It authenticates, nothing more.
Please reply only to the list, not to me personally - unless you
intended it for me personally, in which case, do NOT send it to the list.
One or the other.
J.
