Spammers have finally started sending to email@example.com. Good luck to them, because that address is now history. Although I get a large amount of spam through my business address (which I will not post here for obvious reasons), my "sacrificial address" concept seems to work fairly well.
Regular visitors to Smiffy’s Place may notice a new contact address at the bottom of the page. At the moment, I have to set this address in the database that drives this site. My plan is to improve this process by having a single programme that changes the address in the database, removes the old address from the Postfix mail server virtual users table and inserts the new one. I will document the technique used, as I cannot see how disclosure will benefit spammers.
