=item C<OK>

Return this only from the queue phase to indicate the mail was queued
successfully.

=item C<DENY>

Returning this from a hook causes a 5xx error (hard failure) to be
returned to the connecting client.

=item C<DENYSOFT>

Returning this from a hook causes a 4xx error (temporary failure - try
again later) to be returned to the connecting client.

=item C<DECLINED>

Returning this from a hook implies success, but tells qpsmtpd to go
on to the next plugin.

=item C<DONE>

Returning this from a hook implies success, but tells qpsmtpd to
skip any remaining plugins for this phase.
