They do work with them, and they don't like manitu, either. Btw, I was

Right, but given what whois reports, for all I know, it's somebody with a
home business that can't/won't even afford their own static IP reporting
this. This suggests that it could be one person getting a bunch of spam,
and blocking everyone else by reporting it a few times.

Ok, thanks for that info.

Perfect description.

Right, and since I'm NOT running a business - I broke down and got the
domain when I was about to relocate for the THIRD TIME in < 10 years
halfway across the US, so that I could tell everyone an email address that
wouldn't change again. I dunno that they have a rate that includes a
non-shared mailserver without going to business rates, 10-20 times what
I'm paying now.

No, this is a dozen or two dozen times over the last four years, or more.

I assume you missed the last time I gave a long rant. Allow me to repeat
the relevant part: about a dozen years ago, cogeco, in Canada, was
blocking me from emailing an old friend, and even with him complaining,
this went on and off and on till he simply stopped using them, and used
his professional account.

The reason was that they were blocking roadrunner Chicago. Roadrunner, at
the time, provided a major portion of the city of Chicago with 'Net access
- that's hundreds of thousands of home and businesses, and they'd gobbled
up most of the independent ISPs. We really didn't have much in the way of
other options. What could anyone in the city do?

So instead of blocking domains, they block hosting providers' mailservers.
18 and 20 years ago, when there were lots of independent ISPs, it could
make sense. In these days with most of them eaten, it does *not*.
