>Description:
The current version of SpamAssassin rules includes a rule that scores
very highly any email message with a header Date greater than or equal
to 2010.
In
/usr/local/share/spamassassin/72_active
there is a rule
##{ FH_DATE_PAST_20XX
header FH_DATE_PAST_20XX Date =~ /20[1-9][0-9]/ [if-unset: 2006]
describe FH_DATE_PAST_20XX The date is grossly in the future.
##} FH_DATE_PAST_20XX
which catches mail with a Date including the current year (2010), yet
this rule is scored heavily.
>How-To-Repeat:
>Fix:
There are several options to fix.
(1) add in a local scoring rule like
score FH_DATE_PAST_20XX 0
(2) change the regular expression in the current rule to look another
10 years in the future.
(3) Do nothing and hope that users are all using sa-update which should
have this fixed soon.
Note that this is being actively discussed on the spamassassin
mailing list.
