I know 2.0 is due out soon but I was wondering if anyone has a fix for a problem
I'm having on my home machine.
I have a PC7300 at home and decided to install elm as a suid mailer well
everything is fine execept that if I leave only some mail in the system mailbox
it gets unwritable by the group ( probably because of my umask ) and the
group gets change to my group NOT mail. Well after that any new mail gets
bounced.
First question is, does this happen in 2.0?
My second question is anybody got a fix that I can use while waiting for 2.0?

It should work okay if you setgid to "mail": chgrp mail elm chmod 2755 elm I have a little different problem with permissions... When using Elm, the editor (vi or Lyrix on my system) creates a file in /tmp that is readable by others, thus a security violation. Instead of hacking the C code, I'm waiting for the new 2.0 release. But in the meantime, I made a front end shell script to Elm that says: umask 066 exec /usr/lbin/.elm $* #the real ELm This also fixed the problem with my "mail.sent" file in my home directory being readable by others. (I am on version 1.5). -- Greg

This may have been fixed in later versions. -- Greg #include <pwd.h> struct passwd *getpwnam(); char *getlogin(); struct passwd *pwd; /* orig code chown(infile, userid, getegid()); */ /* new code */ pwd=getpwnam(getlogin()); chown(infile, pwd->pw_uid, getegid());
