That was the original hope -- to get something to fight back with just in Postfix. The sending mail server is at a pretty big "mail services" provider. Which mainly looks like "marketing" services if you ask me. A non local option is to contact the ORIGINAL sender and tell them to get me off their $&$&^$ mailings or get blocked completely. I don't believe for one second that they actually care. But it'll make me feel like I did something. > This could also be a sender that just keeps trying to send the same thing over and over again, an automated process doing the same The fact that it's evenly timed, every 15 mins, says 'automated' to me Thanks all for the comments.
