The way we've done it is to add an extra header field to the email as it goes out such as :
X-TrackID: 24475 That way, as *most* bounce messages send back the header of the email (from looking at our logs it seems to be about 1 in 10 doesn't), we can just use a regex to grab the appropriate ID back (bounce detection written in perl, so perl regex, but you'll get the idea): $email =~ m/X-TrackID:\s*(\d+)/; Once we've got the user ID (or in your case email address) then we can do what we like with it -- set a flag, delete the user, etc etc etc... Modifying the above slightly, you could check for the header field, then use a general regex to parse out an email address from the body if the header's not passed, but be careful cos a lot of bounce messages include things like the message ID or postmaster email address of the undeliverable domain -- you want to make sure you're actually getting the right one. But at the same time, you don't just want to "unsubscribe" _every_ email -- what happens if some oik decides to send an email to the bounce address containing nothing but a huuuuuge list of emails? You don't want to unsubscribe every single one... HTH, Tim. ------------------------------------------------------- RAWNET LTD - Internet, New Media and ebusiness Gurus.
