For elm, I found that it is much much easier to NOT have elm run setgid
(which means in configuring it, you have to say NO to this question).
Then you make the /usr/spool/mail directory o+rwxt, so that everyone can  
read and write into it, but the sticky bit ('t') means you can only modify  
files you own.  If you do this, the mailbox files in /usr/spool/mail  
should have the uid and gid of the user in question, and not have gid  
mail.

[smail seems to give read permissions to the world when creating a  
mailbox, so when you create a new account you should touch the mailbox and  
chmod it to 600 in the adduser script (like mine does!)]

I don't buy this.  The third sentence does not follow from the second.
