After the big discussion a month or so ago, I decided to give spamassassin
another fair try - this prompted by my having created self-imposed problems
getting spambayes to work on my home FC5 pc. I use kmail - supposedly, kmail
detects spamassassin and give you the option of configuring/using it - it
provides training buttons on the menu-bar, so you can go through your inbox
and separate the spam; I also trained on a number of ham messages that had
been filtered into various folders, training on several from each folder.
After intially terrible results, my spam detection crept up to about 80%.
Since I get over 200 spam messages daily, that still would leave over 40
messages to sift through daily, not so great. Today, I finally got Spambayes
running; after initial training on about 200+ messages, I'm already getting
around 95% spam detection...

Am I missing something here? Is there a better way to train spamassassi
Some people find it helpful to change the BAYES_99 test to me equal to the spam cutoff
or slightly below it. If the spam cutoff value is 5.0, set BAYES_99 test
value is set at 5.0 or 4.9.

Another philosophy suggests to periodically retrain spamassassin on spam
that has already been identified as such by spamassassin.

There are many other spamassassin tests you can fool with.

Look at :http://lwn.net/Articles/172491/
and you will see when tested spamassassin beats spambayes in spam
identification. I don't want any flame wars on this but I stick to my
assertion that when used properly spamassassin is philosophically either
equal or slightly better than spambayes in detecting spam. That is,
spambayes's approach is no better than spamassassin so I would expect
comparable results.
