Is it possible to automatically drop/delete all mails send to a specific mail-address while having a catch-all at the same domain?
Should be possible by using a postfix header filter in ISPConfig and a mailbox filter in the mailbox should work as well.
In de Ispconfig manual, under Postfix blacklist (Email blacklist) it says: " smtpd_recipient_restrictions: SMTPD recipient restrictions will put restrictions on what messages will be rejected based on the recipient email address (RCPT TO. Postfix will check whether the message sender (email address, domain, mail server) is included in the blacklist table " This is confusing. if I select "Recipient", does it reject all mails send to the addresses?
