Blocking mailfrom with postfix

Hi experts,

I am trying to create a rule with header checks in postfix but no successfull.

I would to like to block for example mail from: test@test.com
to any email in my domain.

How ?

Thanks
Anderson

This is probably better done with check_sender_access than with header_checks, e.g.:

Code:

smtpd_recipient_restrictions = 
      permit_mynetworks 
      reject_unauth_destination
      check_sender_access hash:/etc/postfix/sender_access

sender_access:

Code:

baduser@example.com    REJECT

Then, run

Code:

postmap /etc/postfix/sender_access
