That is, it makes your messages more difficult to read.
It injects syntax errors into commands and config
file entries that sometimes appear in forums like
this one.  It even breaks URLs.

If you can't shut it off, file a bug.
Email and netnews are plain text media.
Client software that breaks it is monkeywrenching
a well thought out design, out of ignorance and
negligence.  Microsft does it all the time, but
we're supposed to show more respect for our
community.

I'm reading this forum as a newsgroup, on a commercial
netnews provider.  (It wouldn't make much sense to subscribe
to it as an email list.)  The news company's email to news
gateway changes the message IDs.  I think it's supposed to
poison the spam address harvesters.

=20.  Quoted printable is an abomination.

There are dozens of well known, popular DNSBLs.  There are
perhaps tens or hundreds of thousands of private or
unadvertised DNSBLs.  I've tried the ones I can find that try
to map the "dynamic IP" space, because it correlates to the
consumer Microsoft boxes with spambot infections, and none of them
has been worth using.  That's why I asked *which one* you thought
might provide even *usable* coverage for this purpose.
It would save me a lot of work.

"Graylisting" isn't SMTP.  I'm not ready to give upon SMTP.
I'd rather boycott spammer-friendly ISPs until they are forced
to choose between honest people and spam criminals.
