4. Further Configuration

In your /.spamassassin directory, there is a file containing your preferences for SpamAssassin, called user_prefs. It is very well documented, and allows for setting your threshhold, deciding whether or not SpamAssassin modifies the suject field, and whether SpamAssassin puts a full report in the headers or not. Whitelists and blacklists can be stored here. Note that after a certain number of non-spam messages from a particular list, users are automatically whitelisted.

There is very complete documentation for SpamAssassin located at http://www.spamassassin.org.
