It seems there is an issue with the Spamassassin FH_DATE_PAST_20XX test. This test checks whether the email has a date in the future and, if this is the case, raises the message’s score. Apparently, this test is falsely triggered by all emails that have been sent in 2010, producing several false positives. Since, I do not have much time to investigate this issue and to follow the news, I decided to inactivate it until I am certain it has been resolved.

[Update: It has been resolved. Update you SA rules]

To inactivate the FH_DATE_PAST_20XX test system-wide add the following line to the Spamassassin configuration file, usually located at /etc/mail/spamassassin/local.cf:

score FH_DATE_PAST_20XX 0

If you use the spamassassin server (spamd), don’t forget to restart it for the changes to take effect.

As I have mentioned in the update above, the issue has been resolved (Kudos). The Spamassassin developers have released updated rules for the FH_DATE_PAST_20XX test, so make sure you run sa-update:

/usr/bin/sa-update

If you compile your rules, make sure you also run /usr/bin/sa-compile and of course restart spamd.
