All Bayesian filters need trained, and spamassassin is just the most 
popular.  It does no filtering at all until it has looked at a large but 
non-spam (in your opinion) database of emails, and an equally large number 
of what you determine is spam.  

SA installs some scripts to facilitate doing that.  But even so it may 
take your conscious moving of an unwanted message into the spam maildir, 
when a cron driven daily session of sa-learn --ham or --spam directory-to-
inspect might take 20 or more such unwanted messages to build up the 
opinion that hey, this stuff is spam.

In my own script, I clean out the spam directory each time it is run, but 
leave the ham so I can move it back to the desired folder it belongs in.

Everyone has their favorite methods.  I also run a pre-fetch session of 
mailfilter, which can inspect the headers of a message sitting in your 
ISP's mailbox, and it it hits an undesired address, will delete that email 
so that the following session of fetchmail won't pull it, but after 5000 
or so entries in its database, I have discovered there is no way to keep 
ahead of the Dr. Oz spam, his botnet uses a different set of relays about 
every 3 days.  He must have 50,000 or more machines at his disposal.
