Spamassassin 2010 bugfix

Freaking Wildchild — Fri, 01 Jan 2010 11:06:40 +0000

I came home after newyear and was flabbergasted as soon as I saw, I had no mail! With exception of my whitelist, which is bitter small. After reading Slashdot, I’ve noticed Spamassassin has a 2010 bug, dropping legit mails to spam or nowhere; depending on the account settings.

There are two ways to fix this by hand; to keep the ability to thwart mails coming from the future (after 2014 in this case):

Step 1: edit the ruleset file.

With root privileges: Edit the file /usr/share/spamassassin/72_active.cf
Without root privileges: Add to the file ~/.spamassassin/user_prefs

Step 2: find/add or change FH_DATE_PAST_20XX:

##{ FH_DATE_PAST_20XX header FH_DATE_PAST_20XX Date =~ /20(1[4-9]|[2-9][0-9])/ [if-unset: 2006] describe FH_DATE_PAST_20XX The date is grossly in the future. ##} FH_DATE_PAST_20XX

I wish variables could be used in regexps like these, like $year + 2 would be a nice start….

Alternative Step: Automatic update of rulesets

The Spamassassin rules can be updated automatically by executing the following command:

any unix system: sa-update && /etc/init.d/spamassassin reload
Directadmin: /usr/local/directadmin/scripts/packages/Mail-SpamAssassin-3.2.5/sa-update && /etc/init.d/spamassassin reload
admispconfig: /usr/local/admispconfig/ispconfig/tools/spamassassin/usr/bin/sa-update && /etc/init.d/spamassassin reload

Enjoy your mail without spam coming from the future!

02/jan/2010: Thanks go to mike for the even more-fine-grain regexp: 20(1[4-9]|[2-9][0-9])/
