> Those "brief notification" messages must either contain a little information, like a subject line, or people will have to click on them not knowing what they're going to get.

I'd suggest they contain a subject line and sender name. Any obvious spam would then not need to be transmitted over the Net at all, at least to users who care, which would take care of a lot right there!

> Either way, these will become the new method of delivering spam.

But remember that it would be much easier for a responsible ISP to stop this before the worst part of the problem than it is under SMTP. If an ISP detects spam, it deletes the message at the source before most people have downloaded it. If a customer's computer is spamming with its own IM2000 server, it could simply block the receiving port to that IP. Under SMTP, if it was caught at any point after the spam was sent, it's too late.

> If there's an open relay out there for "brief notification" messages, it would have to be closed so spammers don't send fake ones.

It would be impossible to send fake notification messages, because the end-user's box needs the IP of the server from which to fetch the mail!
