Chuck, that suggestion could be useful for me, but I can two bits... I've noticed that some legitimate bulk mailers, like spammers, are completely brain dead when it comes to removing e-mail addresses that have bounced. For example, I saw a spammer consistently using an address that hadn't existed for 5 years in my domain. So now it's a spam trap, but it wasn't just getting spam, it was still getting catalog flyers, "service updates" for a cell phone that would be long gone, and some other member news kind of stuff.
This bad behaviour on their part wouldn't invalidate the test you're suggesting, but it would make me give it a moderate weight. The other false positive I can easily see would be spelling errors. Happens all the time. -----Original Message----- From: Charles Frolick [mailto:[EMAIL PROTECTED] Sent: Friday, August 29, 2003 2:07 PM To: [EMAIL PROTECTED] Subject: [Declude.JunkMail] Possible test suggestion I'm trying to remember if this has been suggested before, couldn't seem to find anything in the archives (probably bad search terms). How about a test similar to MAILFROM but it checks the intended recipients of all local domains and fails if any of them are invailid, ignoring the nobody alias. It could even return the count as weight or a multiplier of count as weight. I can't think of a reason legitimate mail will have more than a couple outside of a mailing list, which, if I'm remembering right, generally only uses single recipients. Pros, cons, extensions?
