I have a home setup where I am using Centos 4.4 as a sort of mail
server. This is what I have done.
I have it configured to pop mail locally. I have fetchmail
configured to dl from my provider my families mail through a cron
job and .fetchmailrc in their home directories. They then pop the
server to retrieve their mail. They send their mail directly through
the provider.
I have been relying on spamassasin on their local boxes to learn and
filter out the spam but find it is only doing about half of the job
even after months of training.
I guess my question is this. Is there a way to do further spam
filtering on the mail server incorporating my method of doing mail
or am I not just doing this right?
My experience is that the version of spamassassin that ships with
CentOS 4 is simply out of date. What works best for me using the Dag
Wieers/RPMforge version (currently at 3.1.7).
Semi-tricky is that fact that it requires some other packages as well.
Here's my /etc/yum.repos.d/rpmforge.repo (which also includes some
packages unlikely to be of interest to you, like cfengine and
conserver):
----- %< -----
# Name: RPMforge RPM Repository for Red Hat Enterprise 4 - dag
# URL: http://rpmforge.net/
[rpmforge]
name = Red Hat Enterprise $releasever - RPMforge.net - dag
mirrorlist = http://apt.sw.be/redhat/el4/en/mirrors-rpmforge
enabled = 1
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
includepkgs = cfengine clamav clamav-db clamav-milter clamd conserver

spamassassin subversion
----- %< -----
Make sure the includepkgs list is all on one line. Then "yum upgrade
spamassassin" should get you the new packages.
After installing the new spamassassin,
1. Run sa-update to grab the latest stock ruleset from
updates.spamassassin.org, though I suggest you read the
sa-update(1) man page first to understand what you're doing.
2. For each SpamAssassin user, at the very least, run (as that user)
'sa-learn --import' to update their Bayes databases. It's probably
most helpful to read the MIGRATION section of the sa-learn(1) man
page. You'll most likely want to disable the fetchmail runs during
the migration.
