public-inbox-learn - spam trainer and remover for public-inbox
=head1 SYNOPSIS
B<public-inbox-learn> <spam|ham|rm> E<lt>MESSAGE
=head1 DESCRIPTION
public-inbox-learn can remove spam or inject ham messages into
an inbox while training a SpamAssassin instance.
It is intended for users of L<public-inbox-mda(1)> or
L<public-inbox-watch(1)>, but not users relying on
L<git-fetch(1)> to mirror inboxes.
It reads one message from standard input and operates on it
depending on the command given:
=head1 COMMANDS
public-inbox-learn takes one of the following commands as its
first and only argument:
=over 8
=item spam
Treat the message as spam. This will mark the message as
removed so it becomes inaccessible via NNTP or WWW endpoints
for all configured inboxes.
The message remains accessible in git history.
It will also be fed to L<spamc(1)> for training purposes unless
C<publicinboxmda.spamcheck> is C<none> in L<public-inbox-config(5)>.
=item ham
Treat standard input as ham. This is useful for manually injecting
messages into the archives which failed the spam check run by
L<public-inbox-mda(1)> or L<public-inbox-watch(1)>.
It relies on the C<To:>, C<Cc:>, and C<List-ID:> headers
to match configured inbox addresses and C<listid> directives.
It will also be fed to L<spamc(1)> for training purposes unless
C<publicinboxmda.spamcheck> is C<none> in L<public-inbox-config(5)>.
=item rm
This is identical to the C<spam> command above, but does
not feed the message to L<spamc(1)>
=back
=head1 ENVIRONMENT
=over 8
=item PI_CONFIG
Per-user config file parseable by L<git-config(1)>.
See L<public-inbox-config(5)>.
Default: ~/.public-inbox/config
