|
8 * Added hpux hacks to set and reset gid to be "mail" as needed. The reset
|
|
|
9 * is necessary so inc'ed mail is the group of the inc'er, rather than
|
|
|
10 * "mail". We setgid to egid only when [un]locking the mail file. This
|
|
|
11 * is also a major security precaution which will not be explained here.
|
|
|
12 *
|
|
|
13 * Fri Feb 7 16:04:57 PST 1992 John Romine <bug-mh@ics.uci.edu>
|
|
|
14 * NB: I'm not 100% sure that this setgid stuff is secure even now.
