  There are a number of methods.  Volume is one.  Content filtering is
another.

  i.e. If the recipient can decide a message may be spam based on
content filters, why the heck can't the senders ISP make the same
decision?

  Why can't ISP's run simple QoS style limiters on outbound email?
For each message that looks like real email, bandwidth goes up, and
delay goes down.  For each message that looks like spam, bandwidth
goes down, and delay goes up.  At no point will any email be blocked.
And the delays will usually be done on time scales that are
unnoticable to people.

  There are MANY ways of dealing with suspicious traffic at the
source.  Dropping the traffic whole-sale is just one of them.

  Cost considerations aside (no one makes money off of email, etc..),
I don't understand why it's considered acceptable Netiquette to send
gigabytes of garbage onto the net, knowing full well that most of it
will be thrown away at the other end.  It's ridiculous.

  That's *exactly* what I refused to say.

  I'm saying that the ISP's MAY CHOOSE to be polite to the rest of the
net, and (shockingly) may want to be aware of what's going on in their
internal network.

  If you're a spammer, it's perfectly reasonable for you to get kicked
off of an ISP (at their choice or yours), because allowing you to spam
usually costs them MUCH more money than they get from you.
