#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.
