At the least, do this:
>/etc/aliases;newaliases
I'd recommend, however, a minimal /etc/aliases file, such as:
red:/var/lib/mail# cat /etc/aliases
# @(#)aliases 8.2 (Berkeley) 3/5/94
#
# Aliases in this file will NOT be expanded in the header from
# Mail, but WILL be visible over networks or from /bin/mail.

#
# Basic system aliases -- these MUST be present.
MAILER-DAEMON: postmaster
postmaster: root
# General redirections for pseudo accounts.
bin: root
daemon: root
games: root
ingres: root
nobody: root
toor: root
uucp: root
# Well-known aliases.
manager: root
dumper: root
operator: root

ls -ld /
Should be 755 root.root .
