-#
-# This plug can be used to train via an arbitrary program that
-# receives the message on standard input. Since sendmail can be
-# such a program, it can be used to send the message to another
-# email address for training there.
-#
-# For example:
-#   antispam_pipe_program = /path/to/mailtrain
-#        (defaults to /usr/sbin/sendmail)
-#   antispam_pipe_program_args = --for;%u
-#   antispam_pipe_program_spam_arg = --spam
-#   antispam_pipe_program_notspam_arg = --ham
-#   antispam_pipe_tmpdir = /tmp
-# will call it, for example, like this:
-#   /path/to/mailtrain --for jberg --spam
-#
-# The old configuration options from when this plugin was called
-# "mailtrain" are still valid, these are, in the same order as
-# above: antispam_mail_sendmail, antispam_mail_sendmail_args,
-# antispam_mail_spam, antispam_mail_notspam and antispam_mail_tmpdir.
-#
-# Alternatively, if you need to give multiple options, you can use
-# the spam_args/notspam_args parameters (which are used in preference
-# of the singular form):
-#   antispam_pipe_program_spam_args = --spam;--my-other-param1
-#   antispam_pipe_program_notspam_args = --ham;--my-other-param2
-# which will then call
