Staring very slow at sending mail and sm-client

The system starting up process took me ages suddently. The system hangs at "enabling swap space" for at least 2 mins, but after that, everything looks fine.
First, modify kernel parameters to disable the graphic booting and reboot.
Now I found that the actuall hanging starting up processes are "sending mail" and "sm-client",which probably are caused by DNS resolving.

You can wait untill the system started up, or just login by ssh from another PC, because the kernel and sshd processes are started already.
more /var/log/maillog
you can see the reason clearly from the log, the reason is your domain name can't be resolved.

Resolutions:
need to modify following two files,
in /etc/hosts,
127.0.0.1 localhost.localdomain localhost
127.0.0.1 goblin.localdomain goblin

in /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=goblin.localdomain
