The other day I was thinking it would be cool if you could detect legitimate replies to mail I send.
Everyone gets spam with subjects like this: Re: some type of trash subject Obviously those are not replies to a message you sent. That got me thinking of ways to authenticate a legitimate reply to a message I sent. I came up with a concept called 'Authenticated Reply Detection'. It uses the Message-ID header to encode some information when a message goes out - no database or saving of Message-ID is required. If/When a reply comes back the details from Message-ID come back in the 'In-Reply-To' header. If validated the message is guaranteed to be a reply to a message I sent, and spamassassin could adjust scoring accordingly. Has anyone ever seen anything like that before for SA? Does it exist already or any type of plugin etc? Regards, Rob
