I have just found out why most of my emails have been getting tagged as spam this year. It's because of a bug in a rule which causes this hit to happen when it shouldn't: "FH_DATE_PAST_20XX The date is grossly in the future". The actual file at fault is 72_active.cf which is a spamassassin rule file and it can be fixed by getting the new file via sa-update.
But I don't understand how to use sa-update. I've run it and I can see all the new rule files in /var/lib/spamassassin/3.002005. However, I think my rules run off the files in /usr/share/spamassassin/. The wiki at http://wiki.apache.org/spamassassin/RuleUpdates#Using_sa-update says NOT to use the "--updatedir" parameter to put updates in /usr/share/spamassassin. So how exactly do you get the new rule files into /usr/share/spamassassin so they start working? Do you just copy them across manually, or is there a way of getting sa-update to do it automatically?
