#ifdef MAILGROUP
/* Revised: Sat Apr 14 17:08:17 PDT 1990 (marvit@hplabs)
* Added hpux hacks to set and reset gid to be "mail" as needed. The reset
* is necessary so inc'ed mail is the group of the inc'er, rather than
* "mail". We setgid to egid only when [un]locking the mail file. This
* is also a major security precaution which will not be explained here.
*
* Fri Feb 7 16:04:57 PST 1992 John Romine <bug-mh@ics.uci.edu>
* NB: I'm not 100% sure that this setgid stuff is secure even now.
*
* See the *GROUPPRIVS() macros later. I'm reasonably happy with the setgid
* attribute. Running setuid root is probably not a terribly good idea, though.
* -- Peter Maydell <pmaydell@chiark.greenend.org.uk>, 04/1998
*
* Peter Maydell's patch slightly modified for nmh 0.28-pre2.
