(sorry if this is a
repost, I dont see my messages coming through...the irony of
spamassassin.apache.org trapping my request for help as spam. I
have snipped the logfile entries which I think were causing it to
be tagged as spam)
All of my messages are being tagged with BAYES_00=-1.9
I have cleared the bayes db (sa-learn --clear), then I manually
trained. Here are the results:
sa-learn --dump magic

Here are two examples it shows that the bayes filter is very
confident these emails are ham:

The spam is learned by a simple bash script. The users (my
family) move spam into a SPAM folder. This script then runs every
night ( I have removed some of the logging lines and comments for
brevity):
#!/bin/bash
# delete messages this old
cleanafter=14
# grab all the user folders
users=`find /var/spool/cyrus/mail -name SPAM -print`
for u in ${users[@]}; do
inbox=${u%/*}
folder=${u##*/}
user=${inbox##*/}
sa-learn --nosync --spam --progress --dir
$inbox/SPAM
sa-learn --nosync --ham --progress --dir $inbox
done
# sync the sa db
sa-learn --sync
