You need to have elm set gid (group I.D.) and in the same group as
/usr/mail with /usr/mail read, write, and executable by group.

Here at our site, with all the problems we have here with students
trying to hack mail, we have modified elm so it doesn't use lock
files, but uses flock(2) exclusively. It is hoped that someday, when I
get the chance, I will do it properly with diffs and send the diffs to
the elm development group, so that in the future, sites that have flock(2)
can have the option to use it exclusively. (provided the changes are
approved.)
