hello all, I have a server with postfix and I want the following setup: 1. Only certain sender addresses can send email to patterned email addresses. For example, [email protected] and [email protected] only allow the following senders
[email protected] [email protected] 2. if any sender other than above address send message to [email protected] or [email protected], I want postfix reject the message, but in the backend, send the message copy to [email protected]. how can I do this? any hints are welcome. Thanks a lot.
