Haven't read those notes, but in my experience using .procmail to dump
all spam into a Junk Mail folder is almost a requirement - otherwise
SPAM keeps finding its way (albeit tagged) to people's mobile devices.
It may take a bit of CPU/disk resources to do, but it saves plenty on
bandwidth/user experience.
