Hello Postfix Experts,
let’s say that domain.com <http://domain.com> is Postfix $mydomain.
I know that it is possible to protect
/etc/postfix/protected_destinations from external senders, as per
https://www.postfix.org/RESTRICTION_CLASS_README.html
But is it possible to limit users from the same domain who can send
mails to an internal email distribution list?
In other words, is it possible to setup Postfix so that
[email protected] CAN send an email to /etc/postfix/protected_destinations
[email protected] CANNOT send an email to [email protected]
[email protected] is a simple Postfix alias.
Thanks for your time,
Ivars
Hi, yes, you can.
main.cf:
smtpd_restriction_classes = insiders_only
insiders_only = check_sender_access hash:/etc/postfix/insiders, reject
...
...
smtpd_recipient_restrictions = check_recipient_access
hash:/etc/postfix/protected_destinations
...
...
/etc/postfix/insiders:
[email protected] OK
[email protected] OK
/etc/postfix/protected_destinations:
[email protected] insiders_only
[email protected] insiders_only
$ postmap /etc/postfix/protected_destinations
$ postmap /etc/postfix/insiders
$ postfix reload
