In Perl:

        $messageid = '<rs-' . time . ".$$\@$HOST>";

where $HOST is set to the local hostname works pretty well.  In shell,
something like:

        hostname=`hostname`
        messageid=`date +%Y%m%d%H%M%S | sed 's/^/<rs-/'`
        messageid="${messageid}.${$}@${hostname}>"

is the equivalent.  The leading "rs-" is just there out of paranoia in
case something else on your system is using the same message ID generation
algorithm.
