- 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.
