it seems Spamassassin has a bug related to year 2010
the problematic rule is FH_DATE_PAST_20XX
just find 72_active.cf file and replace ‘/20[1-9][0-9]/’ to for example ‘/20[2-9][0-9]/’
now, the problem year is 2020 but by then your file will probably get overwritten by your distribution
you can put whatever number instead of 1, not just 2 and make it work longer
or simpler, edit your local.cf and set this rule to have zero score
score FH_DATE_PAST_20XX 0.0
once your distribution fixes this just remove local.cf entry
