How do I configure Postfix to not accept messages for invalid recipients?

  • 772

As with all mail servers, mine frequently receives spam for invalid recipient addresses.

What configuration values will force Postfix to immediately reject these messages? Furthermore, if Postfix is rejecting them and tries to bounce them back to the origin, how do I force Postfix not to bother deferring the bounce message if it isn’t immediately accepted by the origin?

postfix

  1. Set the following options in the /etc/postfix/main.cf

    bounce_queue_lifetime = 0
local_recipient_maps = unix:passwd.byname $alias_maps

    If you are using virtual domain/users you should use virtual_mailbox_maps instead
