I want to reject any inbound email to compromised@example.com, an example more people would want this would be internal distribution groups/aliases.
I've tried header_checks without success:
zmlocalconfig -e postfix_header_checks="pcre:/opt/zimbra/conf/custom_header_checks"
contents of /opt/zimbra/conf/custom_header_checks
/^To:compromised@example.com/ REJECT Mailbox no longer valid
However I still do not get the rejection.
I also tried some of the configuration from Refuse to send email to specific recipients with Postfix since he had things configured in reverse which is what I'm looking for.
zmlocalconfig -e smtpd_recipient_restrictions=check_recipient_access hash:/opt/zimbra/conf/custom_recipient_blocklist
/opt/zimbra/conf/custom_recipient_blocklist
compromised@example.com/ REJECT
This also did not work as intended.
