I have no much idea how did I introduce this at the first place, I have
just purged courier-base{p} and courier-imap{a}.

I don't know in which part I misconfigured, here is the
/etc/network/interfactes (Sorry I changed some part cause my laptop is
not so comfortable to expose itself so much.)

# The loopback network interface
auto lo
iface lo inet loopback
iface eth0 inet dhcp
        dns-nameservers xxx.xx.5.7 xxx.x.5.225
        dns-search eeee.edu

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

I comment the last
iface eth0 inet dhcp
now, it still shows me:



udp        0      0 0.0.0.0:68              0.0.0.0:*
        3481/dhclient
