postfix changes uid/gid to the target user, thus mail spools are mode
0600 (and created that way by postfix)

personally i think this is the only sane way to do things, group
readable/writable mail spools just opens up all user's mail to
everyone if any one setgid MUA has a bug.  

i also use mode 3775 for the spool directory rather then 2775 so if
any setgid mail MUA has a bug im no worse off then the old 1777 mail
spools that are still commonly used.
