IF you can rate-limit them across the whole Internet, If you limit 2 million machines to 20 msgs/day per mail server you are back up to your 10 Billion msgs/day mark. This is where DCC or other distributed checksum systems come into play.
My point was that there's no real *need* to distinguish between a legitimate user sending 20 emails and an 0wned box sending 20 emails, as the distinction is "legitimate 20 emails" versus "0wned 20K emails".
If I were to only give my users 20 outbound connections/day, there wouldn't be a per-mail-server issue. Whether I can make such a policy stick is another question entirely.
I sent more than 20 mails in the last hour. Given that I have a local mta each of those results in a seperate connection attempts to the machine I use as smart-host. I'm sure I could batch them all up and send them at once thereby returning to my uucp days, but bleh, that really breaks up the pattern of back-and-forth communication that we've gotten used to. There's a bunch of forces pushing in various directions that make email less usable for me and I assume everyone else... The big one is spam, restricitive mta behavior is another, and there are others. When my mta becomes more selective about what senders I choose to accept mail from or in this case when or how often, then eventually I lose mail from people I would otherwise have communicated with. That's frustrating becuase it's as disruptive, if not more so than having a mail box full of crap. Eventually I suspect I'll be forced to abandon the rfc2821 email system as a communications tool entirely, and brick myself up in the cellar, but I actuallly liked it as a tool when it worked. joelja
