SpamAssassin FH_DATE_PAST_20XX bug

Starting with January many I had many complaints from customers regarding legitimate mail marked as SPAM hosted on Plesk/SpamGuardian machines.

After a small investigation I’ve found the problems were from SpamAssassin’s FH_DATE_PAST_20XX rule bug that caused mails to receive a high score if date is past 2010-01-01.

I didn’t wanted to run sa-update, so I’ve created a config file to ignore this rule (I do love stability, so I’m more conservative ) :

[root@apollo ~]# cat /etc/mail/spamassassin/fh_date_past_20xx_fix.cf
# https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6269
score FH_DATE_PAST_20XX 0.0
