Thanks for the kind comment! The advantage of creating an alias which is disabled is that the message is rejected at the SMTP connection stage. This means that it's just a non-existing address for the sending system and does not generate any other internet traffic. If you instead try to reject an email with a rejection message, that rejection might get sent to an innocent third party if a spammer uses a fake return address -- see
