Because there are typically only 2 steps where the mail is handled as
mail, rather than routed raw packets. (Ignoring redirected mail and such)
The user's "outgoing mail server" and the destination domain's mail
exchanger are those two steps. Both hosts *should* have controls in
place which evaluate and limit what is accepted and what is passed on.
Transactions per second per submitting host is available as a control.

If any majority percentage of mail servers used the available
anti-spam software and safeguards, there wouldn't *be* a spam industry.
The root issue is the same as it ever was - uninformed and apathetic
administrators.
