does your bayes_path statement end in /bayes_ ?
Note that bayes_path is both a path, and a start of a filename. Bayes will fail if the literal path is a directory name alone.
I ran sa-learn on the test spam and nospam.txt files, and the bayes_ db files were created.
also - is it sufficient to enclose all the escaped spam and ham into respective messages to train SA with, eg. can sa-learn learn from one message with a bunch of enclosed messages? i will be re-sending the FPs and FNs via outlook to special accounts on the SA server.
sa-learn can only learn properly from ORIGINAL messages or spamassassin's own encapsulations in their complete original form as generated by SA. Forwards, attachments generated by anything but spamassassin itself, etc are not appropriate training data.
SA can recognize it's own encapsulations, but if you feed it messages generated by your mailclient sa-learn cannot magicaly distinguish between a spam message with attachments, and a non-spam message having several spam messages attached to it.
If you want to do some kind of attachment scheme, you'll need an external tool to strip off the attachments and feed them to sa-learn.
i have started using rules like backhair, antidrug, etc. i have about 20 rules in there, is it bad to use so many? i've definitely noticed reduced spam getting through, but had to whitelist_from on some FPs...
Not really, unless you get load average and/or false positive problems. It's really a matter of configuring SA to meet _your_ needs.
Disclaimer: I wrote antidrug, thus have some natural bias.
