group ID bug in "msg" mailer

[Cpt Brian Boyter]

I recently installed "msg" on an AT&T 3B2 and uncovered the following
problem...   I don't know if everyone has this problem...   when you
quit "msg" and are deleting all the files in /usr/mail/user, "msg"
deletes the /usr/mail/user's file, then creates an empty file in its
place....   this new file has a group ID the same as the user but the
group ID should be "mail" or else the mailer cannot append incoming
mail...

The solution is to modify leavembox.c:
	Change:  chown(infile, userid, getgid());
	to:      chown(infile, userid, getegid());

Then in the Makefile where msg is installed:
	Change from:  chmod 4755 ${DEST}/msg
	         to:  chmod 6755 ${DEST}/msg
	        add:  chgrp mail ${DEST}/msg

Hope this helps...
Your old buddy,
