I think I know one reason. If you cannot access the chgrp command (in
fact in C, the chown() instruction), the problem happens. When you
quit elm, it try to restore the group file to the mail group. Of
course, in that configuration it can't. On my machine, the group of my
mailbox becomes my group. The trouble is that right access are read for
the priviligied group, so when it switches to my group, anybody in my
group can read my mailbox !
For this case the solutions are :
-	unset all the read bits for your group and the priviligied
	group for your mailbox file, after the first "restoring
	protection" problem. You must configure as well all the mail
	readers you may use to keep your mailbox file even if it's
	empty. So, you won't need to bother the read bits later.
	Otherwise, when a new mailbox file will be created, the problem will
	happen again.

OR

-	Ask your administrator to install the executable. Elm will own
to root, with a sticky bit (you'll will have to recompile elm to
switch a flag in the configuration as well ). Normally, root has
access to the chown() instruction (!). But it will have to prevent
from opening a shell via ELM (guess why....).

As for me, I use the first solution, and it's work fine. But I must
warn my friends when they use it for the first time.

Pleased to help you.

Marc.
