mail locking

[Phil Ngai]

Some time ago there was discussion on the proper mode of /usr/spool/mail
and it was pointed out that /usr/ucb/Mail does its locking there so it
needs to be writable. Someone said they moved the locking to /tmp.

Isn't it also necessary to worry about the locking protocol used by
/bin/mail, which /etc/delivermail uses for local mail delivery?
