Steve:
I haven't installed the server, but I figure that the people who did
install it here at Qualcomm knew what they were doing, so I took a look
at the permissions on one of the major POP3 servers:
% ls -lgd /var/spool/mail
drwxrwxrwt 2 root solstaff 23040 Nov 19 21:08 /var/mail/
so it is 1777 root.solstaff, where solstaff is an admin group. You
could probably make it wheel or mail group. This makes permissions
exactly the same as the /tmp directory. So any user can create a file
there, but can only access their own files. This is necessary because
popper creates a mail lock file there as the user. I suppose you
could probably change the source so it makes its lockfiles in
/var/lock.
Hope this helps...
