Parent article: 82% of email is spam

>Say a user of an ISP sends a million spams. All million (short) notification messages go out to the clients. BUT, someone at the ISP would almost certainly get some clue rather quickly that a spam was sent. *ZAP* and the message is gone from the ISP's server, and whoever hadn't checked their mail yet will be fortunate enough not to see it or waste bandwidth downloading it!

Except you are forgetting one very important point.

The majority of these spams now contain unique subjects and/or bodies, be it via random dictionary words or whatever. So much to only one copy, eh?

1. These "unique" subjects are only to get around mail filters with SMTP. I don't think those type of filters will be as necessary with IM2000.

2. In the long run it's no real disadvantage over SMTP even if you *do* have to store a separate copy for each recipient. And, if joe@isp.com sends a million distinct messages, some flag would still be raised, and it would be easy for an admin to nuke all his messages.

Heck, you could set a space limit for outgoing mail ... maybe 100MB or so (up to the ISP of course). That should eliminate a million distinct messages.
