Depending on your installed software there really can be a _lot_
of places where your hostname and domainname are used. Nearly all
network packages like s(end)mail or ppp may have your host information
somewhere. As Debian still lacks a centralized network setup tool you
will have to find all the files by yourself. Don't trust suggestions
like "Edit /etc/hostname and all is done"! Instead use grep!
As root do a
# grep <yourhostname> `find /etc/` | less
This will give you a list of all the files where your hostname is used.
You have to be root because some of the configuration files are only
readable to root (like /etc/ppp/*)
The list might look like this for my hostname.domainname fliwatut.scifi:
#------------------------------------------------------#

/etc/apache/httpd.conf:ServerName fliwatut.scifi
[...]
#------------------------------------------------------#
The next thing to do is backup and then edit all the files carefully and
changing the names where appropriate. For some of the files you will
have to run configuration programs again. Sendmail for example will have
to build a new sendmail.cf out of the file sendmail.mc and so on.
