Is iptables running?
# lsmod | grep ipt
# service iptables status
# iptables -L
Is Sendmail/some other MTA running and listening on port 25? Can you
connect locally when SSHed onto the system?
# ps auxw | grep mail
# netstat -ln | grep :25
# telnet localhost 25
Is named running and listening on port 53?
# ps auxw | grep name
# netstat -ln | grep 53
Has anything been updated on the system recently?
# rpm -qa --last | tac
