What do you think?
Adding a Message-Id: header may be easy.

Some servers are rejected, when it is announcing itself as an IP address... as our class does...
See https://major.io/2006/12/26/fixing-invalid-helos/
So it may not be enough.

Could you try to add a Message-Id: header, and see if spamassassin prefer the new layout?

I was talking about the message I received when I registered to this forum (so it's not me to add the Message-Id).

I also hate those tricks used to guess who is a spammer and who isn't but nowadays, if you want your emails to arrive, you should comply to some of those tricks.
