=head1 NAME
connection_id - plugin to demo use of the connection id
=head1 DESCRIPTION
A qpsmtpd plugin which replicates the built in logging functionality, which
is to send all logging messages to STDERR below a specific log level.
This plugin differs from logging/warn only by using the connection id
instead of the pid to demonstrate the effect of different algorithms.
=head1 INSTALL AND CONFIG
Place this plugin in the plugin/logging directory beneath the standard
qpsmtpd installation. Edit the config/logging file and add a line like
this:
logging/connection_id [loglevel]
where the optional parameters C<loglevel> is either the numeric or text
representation of the maximum log level, as shown in the
L<config.sample/loglevel> file.
