Hello Postfix Experts, let’s say that domain.com is Postfix $mydomain. I know that it is possible to protect l...@domain.com <mailto:l...@domain.com> from external senders, as per https://www.postfix.org/RESTRICTION_CLASS_README.html <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 us...@domain.com <mailto:us...@domain.com> CAN send an email to l...@domain.com <mailto:l...@domain.com> us...@domain.com <mailto:us...@domain.com> CANNOT send an email to l...@domain.com <mailto:l...@domain.com> l...@domain.com <mailto:l...@domain.com> is a simple Postfix alias. Thanks for your time, Ivars
