I like this idea.
Is this the right implementation?
Thank you very much
/etc/postfix/main.cf:
-------------------
smtpd_recipient_restrictions =
reject_non_fqdn_recipient
reject_non_fqdn_sender
reject_unknown_sender_domain
permit_mynetworks
check_recipient_access hash:/etc/postfix/valid_users
PREPEND X-Bad-Recipient: Yes
....
permit
header_checks = regexp:/etc/postfix/header_checks
/etc/postfix/valid_users
---------------------------------
[email protected] OK
[email protected] OK
/etc/postfix/header_checks
---------------------------------------
/^X-Bad-Recipient: Yes$/ REJECT
