in dovecot/conf.d/90-plugin.conf i have plugin { # man antispam #setting_name = value antispam_debug_target = syslog antispam_verbose_debug = 1

  antispam_backend = pipe antispam_signature = X-DSPAM-Signature # action to take on mails without signature # (used with any backend requiring a signature) # (we recommend only setting this to 'move' after verifying that the # whole setup is working) # antispam_signature_missing = move # move silently without training antispam_signature_missing = error

  antispam_trash = Trash antispam_spam = Junk antispam_pipe_program_spam_arg = --spam antispam_pipe_program_notspam_arg = --ham antispam_pipe_program = /usr/bin/sa-learn antispam_pipe_program_args = --username=%Lu }

it seems to be going into the database ok but it doesn't seem to be applying anything it is learning.  might there be some configuration option missing?
