Remember Y2K? Well, this isn’t anything like Y2K, but it could result in SpamAssassin incorrectly tagging legitimate mail as spam.
In short, the SpamAssassin FH_DATE_PAST_20XX rule adds 3.4 points to mail dated 01-01-2010 and later.
This was reported as a bug at the SpamAssassin site:
https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6269
Promptly at the start of the new year, all mails started getting an extra 3.4
points based on FH_DATE_PAST_20XX:
The quick fix for VPS accounts is to edit the FH_DATE_PAST_20XX rule in the following file:
FreeBSD /usr/local/share/spamassassin/50_scores.cf
Linux /usr/share/spamassassin/50_scores.cf
and change the following line:
score FH_DATE_PAST_20XX 2.075 3.384 3.554 3.188 # n=2
to:
score FH_DATE_PAST_20XX 0 # n=2
Verio is currently working overtime on the problem and expect a dist to go out in the next 12-24 hours.
