well, the web server stuff you can use apache's vhost options for. For mail,
if you're using sendmail then in your .mc file have something akin to the
following:

Cwmailhost.proteome.org.au
Cwmail.proteome.org.au
Cwproteome.org.au  

(note that if you put those in then I'll get a tad annoyed since it's my
server ;>)

You'll need cnames too - who's your friendly DNS admin?

For apache, use something similar to this:

NameVirtualHost 137.111.176.200
<VirtualHost 137.111.176.200>
        ServerName      chef.proteome.org.au
        ServerAdmin     webmaster at chef.proteome.org.au
        DocumentRoot    /usr/local/httpd/htdocs
        ErrorLog        logs/chef-errors
</VirtualHost>
<VirtualHost 137.111.176.200>
        ServerName      www.proteome.org.au
        ServerAdmin     webmaster at www.proteome.org.au
        DocumentRoot    /usr/local/httpd/htdocs/current_www.proteome.org.au
        ErrorLog        logs/www.proteome.org.au-errors
</VirtualHost>
<VirtualHost 137.111.176.200>
        ServerName      test.proteome.org.au
        ServerAdmin     webmaster at www.proteome.org.au
        DocumentRoot    /export/home/system/jcm/APAF/chef/new-www
        ErrorLog        logs/test.proteome.org.au-errors
        alias /images/  "/export/home/system/jcm/APAF/chef/new-www/images/"
        <Directory "/export/home/system/jcm/APAF/chef/new-www/images">
                Options Indexes Multiviews
                AllowOverride none
                order allow,deny
                allow from all
        </Directory>
</VirtualHost>
