Not to start an argument or anything, but I share the view that the only
mode 1777 directory on the entire system should be /tmp.
Any mode 1777 directory has the potential of being filled up (by anyone
who wants to), thus rendering the partition useless for valid applications
- I could fill up the drive with any old file in /var/spool/mail if its
mode 1777, and from that point on, nobody gets any mail.
Group mail, and g+w, is, in my opinion, the more sensible protection
scheme. Opinions will vary :)
