When i'm logged in as root, mail works perfectly, but with any other user it doesn't. Here is output of the command: mailx -v -s test firstname.lastname@example.org < /dev/null
bash-2.03$ /etc/mail/sendmail.cf: line 0: cannot open: Permission denied
I'm running sendmail 8.12.11 ... I've tried so many things. its driving me insane.
