There isn't anything "loaded" about it, it's merely my experience.  I
probably don't have the correspondence anymore because it was long ago,
and IIRC it involved having to use a web form they had because I
couldn't send them mail, so at least that part of the conversation won't
have been preserved anyway.

What is it you don't understand about this?

My point remains.  It doesn't matter whether I mentioned to have changed
the configuration of Spamassassin or not.  IIRC, I haven't even
mentioned whether I use it or not.

You're the one who brought it up.

You've made your decision about what people should do and what mail to
accept.  Apparently you created and use the table to efficiently have
your decision applied by software. That is your decision, not mine.  If
I was using your mail server, you would be the one to decide what mail I
can receive and what not.  If I was using your table with my MTA to
block mail, you would be the one to decide what mail I want to receive
and what not.

They are merely examples for cases in which the decision of what mail I
want or can receive would be made by someone else.  There's no need to
look at the file for that.

That's nice :)

You're making lots of assumptions and judgements without having the
necessary facts, and you're seeing only what you want to see.
Pretending that everyone who doesn't have the same opinion you have is
a paranoid troll and doesn't have a clue what they're talking about
isn't helping anything.
