Default Change Hostname

I am running the VMTN of the ISP Config running on Debian. Everything is functioning, but the system is still named server1.example.com. I would like it to be mail.cass.lib.mi.us. Where do I need to change this?

My outgoing mail is being rejected because:

the host gateway-a.comcast.net[] said:
521-EHLO/HELO from sender does not map to
server1.example.com in DNS 521-sending machine name must be provided as a
fully 521-qualified domain via EHLO/HELO command. 521-see section
and 4.1.4 of RFC 2821 521 521: Please see
http://www.comcast.net/help/faq/inde...il_Policy18784 for
more information.

Thank You for your help.

Modify /etc/hosts, then run
echo mail.cass.lib.mi.us > /etc/hostname
and reboot the server.
Afterwards, check your hostname by running
hostname -f
