Hello Postfix Experts, let’s say that domain.com is Postfix $mydomain. I know that it is possible to protect [email protected] <mailto:[email protected]> 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 [email protected] <mailto:[email protected]> CAN send an email to [email protected] <mailto:[email protected]> [email protected] <mailto:[email protected]> CANNOT send an email to [email protected] <mailto:[email protected]> [email protected] <mailto:[email protected]> is a simple Postfix alias. Thanks for your time, Ivars
