The spamassassin on my server is 3.2.5 and is stock CentOS 5.x. I do apply updates regularly.
Most of my legitimate contacts are either whitelisted or sorted into folders before spamassassin sees them, but I have noticed an increasing amount of legitimate mail marked as spam.
One issue seems to be the FH_DATE_PAST_20XX rule. I was able to fix that via running sa-update as root per http://wiki.apache.org/spamassassin/Rules/FH_DATE_PAST_20XX
Should the rule be fixed in the actual RPM though since it is past 2010?
Secondly a lot of mail is marked due to
DNS_FROM_OPENWHOIS
In SpamAssassin 3.3 and later, that rule is removed because: Status of bl.open-whois.org: DEAD
http://wiki.apache.org/spamassassin/Rules/DNS_FROM_OPENWHOIS
Shouldn't that rule then be removed from the CentOS RPM? I think I figured out how to remove it manually (give score of 0.0 on trigger) but if it doesn't work, it should be patched out of the CentOS RPM, no?
Will CentOS patch it w/o rhel patching? IE where should I search for bug reports and file a bugzilla?
