Auth is when the spammer wants to send mail through your box to (say) mail.com

If you want to stop incoming spam to your domains the best way to go is to use

LOST #017     -**< Sub : Additional consoles >**-
To add more consoles to the default 6, edit /etc/inittab. To
lines looking like this:
6:23:respawn:/sbin/getty tty6    | Do not cross 11 because
                                 | the last free tty is
... append something like:       | needed by X. Anyway,
7:23:respawn:/sbin/getty tty7    | for most boxes, 10 is
8:23:respawn:/sbin/getty tty8    | good enough
