Well, there's only one difference - world write permission.  As I
understand it, procmail assumes the userid of the recipient, but
retains (or at least should have) group-id of mail, which has write
permission on /var/spool/mail.  BTW, it actually writes to /var/mail,
but that's a symlink to spool/mail, but that should make no
difference.  So the question may well be, what is the group ownership
of the procmail process.  Maybe I'll call a script from .procmailrc to
report the GID.
