           );

           # For use in an individual filter module:

       This class is an I/O handle logger class for use with Courier::Filter and its filter
       modules.

   Constructor
       The following constructor is provided:

       new(%options): returns Courier::Filter::Logger::IOHandle
           Creates a new logger that logs messages as lines to an I/O handle.

           %options is a list of key/value pairs representing any of the following options:

           handle
               Required.  The I/O handle or IO::Handle object to which log messages should be
               written.

           timestamp
               A boolean value controlling whether every log message line should be prefixed with
               a timestamp (in local time, in ISO format).  Defaults to false.

   Instance methods
       The following instance methods are provided:

       log_error($text): throws Perl exceptions
           Logs the error message given as $text (a string which may contain newlines).  Prefixes
           each line with a timestamp if the "timestamp" option has been set through the
           constructor.

       log_rejected_message($message, $reason): throws Perl exceptions
           Logs the Courier::Message given as $message as having been rejected due to $reason (a
