Maildir permissions

[Stephen Froehlich]

My mail server will be located in the office with all of the staff.  Some or
all of them may have a need for terminal access to the box.  While I
generally trust them (enough that I seriously doubt that they'll try to
truly hack the machine, plus none of them have the skills to hack it), I
want to take the general precaution of making the maildirs readable only to
their owners (700).  Will this cause qmail any fits?
