in the spirit of your last quoted sentence
just above, after getting Spambayes working yesterday afternoon, and
training on a couple of hundred messages, I came home this evening and
found only two spam mails in my inbox - there were 313 classified spam
mails in the trash, and after going through those, there was only one
false positive, and that was from a commercial advertising list I'm
subscribed to - I guess my solution ain't broke either...

Sounds like it isn't. Double check that you do not see any "ALL_TRUSTED"
messages. That means SA could not guess your "trusted" mail server(s).
And that "trusted" is a rather loose trust. It's the furthest our from
your site that all email passes through and you trust not to lie to you
about the message headers it inserts. In my case that's the Earthlink
servers and my own machine. (Fetchmail often confuses poor little old
SpamAssassin. So I set it explicitly.)

For mailing lists to which you are subscribed you can use the
"whitelist_from_rcvd", which says you are whitelisting messages that
claim to come from a sender and always goes through a specific mail
server name.

I guess I was a little ambiguous. Once I got Spambayes running, I turned off
Spamassassin. The results above were from Spambayes processing alone, and
that after less than 24 hours of running with very minimal training. Since
about 7 hours ago, I've gotten one additional spam in my inbox, and 97 spams
diverted to trash - no false positives. I'm confident that performance will
get better over the course of the week, as I train on some more mail.

Regarding mail-lists and other filtered mail, the way Kmail works is that my
spam filters are last in the filter chain, and most of my filters are
configured to cease the processing of a message once it matches a filter -
each list I belong to gets its mail filtered to its own folder, and those
filters are configured to stop processing the message once it's filtered; in
fact, most of my ham mail never gets to the spambayes filter - it gets
diverted to a folder and removed from the processing chain - it makes for a
pretty fast spam filtering setup - this wouldn't word in every scenario, but
it works well for me.
