That's not restricted to LMTP aware mail transport. Every mail transport
in sendmail can be configured to handle multiple recipient.

See "/usr/include/sysexists.h".

Like this?

#!/bin/sh
export PATH=/bin:/usr/bin:/usr/local/bin:/usr/pkg/bin:/sbin
export PROCMAIL=/usr/pkg/bin/procmail
if [ ! -x $PROCMAIL ]
then
 exit 75
fi

if [ `sysctl vm.loadavg | awk -F : '{print $2*100.0}'` -gt 800 ]
then
 exit 75
fi

exec $PROCMAIL $*

exit 75

If our "mail.local" would support LSMTP what would be the backend it can
talk LMTP to?

	Kind regards
