+=head1 DESCRIPTION
+
+This plugin enqueues mail from qpsmtpd into Exim via BSMTP
+
+=head1 INSTALLATION
+
+The qpsmtpd user B<must> be configured in the I<trusted_users> setting
+in your Exim configuration.  If it is not, queueing will still work,
+but sender addresses will not be honored by exim, which will make all
+mail appear to originate from the smtpd user itself.
+
+=head1 CONFIGURATION
+
+The plugin accepts configuration settings in space-delimited name/value
+pairs.  For example:
+
+ queue/exim-bsmtp exim_path /usr/sbin/exim4
+
+=over 4
+
+=item exim_path I<path>
+
+The path to use to execute the Exim BSMTP receiver; by default this is
+I</usr/sbin/rsmtp>.  The commandline switch '-bS' will be added (this is
+actually redundant with rsmtp, but harmless).
