This has been the crux of the problem all along, and one of the reasons

they are being inundated by spam. The spam problem is caused by ISPs
who allow mail to enter the network without sender authentication. If
all ISPs required sender authentication, we wouldn't have this problem.
Do we really believe this is true? As far as I've been able to tell,
spammer accounts get closed ASAP, as soon as they are reported.
Having your account closed within hours of sending spam is just a
cost of business for a spammer. That's why ISPs have had to resort
to blocking port 25.
Also, if all ISPs required sender auth, spammers would masquerade as ISPs.
And who provides authorization for all ISPs?
