On Plan 9, 'mail' is a shell script that invokes either nedmail(1) or marshal(1), depending on the flags it consumes. The nedmail program is nearly identical, from a user interface standpoint, to the mail command that shipped with the 8th edition of Research UNIX. It remains part of the same (though evolved) e-mail processing system, upas. Ned is a little different than mailx(1), but it's probably just about what you're looking for. Plan 9's mail system itself (upas) relies heavily upon upasfs(4), filter(1), and simple rc scripts, which make even complex tasks like custom spam filtering and automatic mailbox management trivial. sl
