What do you do when a subject line is longer than 78 characters?
A. Reject

Accept, absent some actual spam sign.
Note that the 78-character recommendation is not applicable to logical
(decoded and unfolded) header fields but only to lines in the
uninterpreted & unmodified transport format. To catch that in SA, a test
would be something like:
header LONG_SUBJ_LINE Subject:raw =~ /.{79,}/m
And that will match mail that many people really want to not be blocked.
