Expanding this a bit further, the safest policy is to never accept any
email at all from HostPapa ranges. Extremely minimal loss, in fact zero
loss for almost anyone. Very high gains.

We concur. During August, there were days of nothing... and then there
were days of tens of thousands of spam. The former were firmly in the
minority.
I also looked at the domains for which there were DKIM matches in

All of them are on the Spamhaus DBL.
If you want people to accept your mail, find a provider that takes
mail security at least sort of seriously. Yes, they exist.
Seconded.
Best,
