Full Discussion: sendmail doesn't work for root
Operating Systems Linux Red Hat sendmail doesn't work for root Post 302678259 by Corona688 on Friday 27th of July 2012 01:30:06 PM

It's telling you the problem -- /etc/mail/trusted-users or /etc/mail is world-writable. Someone must have used the magic sledgehammer, chmod 777-ing it in the past in a misguided attempt to fix a 'problem'.

When something is running as root, loose permissions are a big deal. Anything could inject malicious contents into there and mislead a root daemon, possibly executing arbitrary commands or escalating permissions. So it does checks on it that it wouldn't when running as a limited user.

Reduce the permissions to what you actually need.

pam_console_apply

pam_console_appy(8)					   System Administrator's Manual				       pam_console_appy(8)

NAME

       pam_console_apply - set or revoke permissions for users at the system console

SYNOPSIS

       pam_console_apply [-r]

DESCRIPTION

       pam_console_apply sets or resets permissions on devices in the same manner as pam_console.
       If  /var/run/console.lock  exists,  pam_console_apply  will grant permissions to the user listed therein.  If the lock file does not exist,
       permissions are reset to those listed in /etc/security/console.perms, which should be configured to set permissions on devices so that root
       owns them.

ARGUMENTS

       -r     Signals  pam_console_apply to reset permissions.	The default is to set permissions so that the user listed in /var/run/console.lock
	      has access to the devices, and to reset permissions if no such file exists.

FILES

       /var/run/console.lock
       /etc/security/console.perms

SEE ALSO

       pam_console(8)
       console.perms(5)
