The other problem on a small number of messages was
RCVD_DOTEDU_SHORT.  I realize this must have passed masscheck, but
getting a message of 1-1.5 kB from an address in .edu is to me not at
all suspicious, and 2.5 points is a lot for something likely to
appear in legitimate mail.  (In my case it was a notification of air
conditioning shutdown in a particular building, and that's all there
was to say.)

Score limit adjusted.

Thanks.

Do you know whether it happened to hit
ALL_TRUSTED? I added an exclusion for that.

It did not hit ALL_TRUSTED, and I'd say that's not really wrong.  The
edu in question has outlook hosted mail which has a lot of servers.  I'm
not actually part of the edu, but am on some lists, and have something
to do with it.

I expanded trusted_networks and then it did hit, but the rule still
fired.

That exclusion won't be published until sometime today.

I wasn't suggesting expanding ALL_TRUSTED, I was just curious as to whether you had a relationship to the school and had added their MTAs to your trusted list because of that.

 I will see if after the regexp fixes just made arrive on my
system, it's still the case.

I also modified the header check to restrict it to .edu RDNS, so if their email is hosted by Outlook it probably isn't going to hit any longer anyway.
