How would I go about blocking mail to a valid address if it is sent from a user on my postfix mail server.
For example, let’s say I have [email protected] and that address is only for people outside to send mail to, so when a local user or a user in virtual. (Those users have to use submission ports 587 or 465) send a mail to that address, I would like it to be rejected with a message like "REJECT This email not for internal use". And is the answer different if example.com is on a different server but I still don’t want users on this mail server so be able to send email to it? How about if there is a specific list of users who are not allowed to send mail to that email address? (Trying to cover all the bases here) -- Tina... homecoming is spelled c *O* m
