In sendmail, I can have a catchall address and reject email going to certain addresses in my aliases or virtusertable files:                        error:5.1.1:550 User unknown                     michael                       michael                     error:5.1.1:550 User unknown                       error:5.1.1:550 User unknown                        error:5.1.1:550 User unknown                           catchall

But the above doesn't work in the postfix maps - it tries to deliver to the error: address.

What's the right way to accomplish this in postfix?

This can be accomplished using the check_recipient_access directive (

Add a file that lists the email addresses (followed by reject) and point the above directive to that file.

e.g. check_recipient_access hash:/etc/postfix/deny


denied_user@domain.tld reject

Remember to reload your configuration files - and perhaps restart postfix.
