I am trying to use regexp to block mails from specific domains to specific users (and let other users receive it).
I need to merge (logical AND operator), something like: /^From:.*\@.*domainsource.tld/ REJECT No Unrequested mail Please /^To:.*\@.*domaindest.tld/ REJECT No Unrequested mail Please For my needs I want these rules evaluated in AND. How can do this with a valid rules in my /etc/postfix/header_checks? If there is a better solution ... ;-) Thanks, B.
