No, that was intentional based on a combination that was fairly spammy at the
time. The scored version has exclusions for ham hits and is doing fairly well
in masscheck:

I've added another current ham exclusion to reduce the FPs further.

It also matches on spam having good message IDs:

https://ruleqa.spamassassin.org/20211114-r1895009-n/__MSGID_OK_HOST/detail

If __MSGID_OK_HOST + other rules hit well on spam and poorly on ham then that
combination is a useful spam sign even though the single rule isn't useful by
itself.

The fact that a rule hits ham is not, by itself, a problem. Has this rule been
contributing to hams being scored spammy?

Rule discussions should take place on the Users mailing list, please follow up
there.
