If your systems are running Spam Assassin, then legitimate e-mail having a date after Jan 1, 2010 may see a higher than normal spam score.
This could be due in part to the FH_DATE_PAST_20XX rule in Spam Assassin
which adds a spam score to all messages with a date header after 01/01/2010.
The rule was was designed to identify spam which was dated sometime in the distant future, unfortunately in which present day has caught up to.
To fix this issue, you have 3 options available:
Note 1: Keep in mind that this only fixes the problem until 2020. You might have to come back here in 10 years!
Note 2: If you have previously disabled this rule, you might want to revert your changes
