Unfortunately most of the ip addresses do have reverse lookups.
On the other hand, I do see that some have common domains. So I could
use block by domain using sendmail.
Heck, maybe I should just block the whole country. :)

Do you at least verify the reverse lookup? That already stops a lot of such
networks.
I've been using spamassassin for almost several decades, and I've never
noticed anything like this. I don't understand why the spam continues
to be sent over and over. I do reject emails with a very high spam,
which these spams have. So I tried changing my configuration to discard
the email instead, hoping the spammer software would decide that the
email had been received. This didn't help. I'm curious if anyone is
noticing this spam. Thanks. - Mark
This takes a while (afaik months at least).
