We are using postfix for mail delivery. I would like to know if it is possible to autoreply to mails saing that a user have moved email address. Ideally the user should not need an user account.
So the case is:
someone sends a mail to email@example.com, but he has recently stopped working here. We would now like to reply that firstname.lastname@example.org does not exist anymore but his new mail is email@example.com.
