I found a plugin for dSPAM on this mailing list (http://thread.gmane.org/gmane.mail.imap.dovecot/4632/focus=4632) that was very useful to me.  I just modified the code to work for SpamAssassin instead.  The purpose of this plugin is to watch the mail that is in the user’s spam folder.  If the user manually moves a piece of mail into the spam folder then the mail must have been spam that was incorrectly classified.  This plugin causes SpamAssassin to relearn that mail as spam.  Anyone else who finds this functionality useful is welcome to follow the link below.
