You may want to change the host name of your VPS to your own domain name from the domain name that is automatically assigned when your VPS was created.
You may also want to customise all the screens and templates in DTC with your own branding.
Choosing a host name
Your host name needs to start with a subdomain of your domain name. eg mx.example.com
It is recommended that you use mx. If you don't use a subdomain then you can upset the mail system on your VPS.
To change the host name
What you should do is a grep -R in /etc to find all the files that contain the hostname, so you don't forget an instance of the hostname.
grep "oldVPSHostName" * -R
eg.
root@myVPS>_ /etc# grep "oldVPSHostName" * -R
hostname:mx.oldVPSHostName.tld
hosts:192.168.1.1 mx.oldVPSHostName.tld dtc.oldVPSHostName.tld oldVPSHostName.tld
mailname:mx.oldVPSHostName.tld
motd:Linux mx.oldVPSHostName.tld 2.6.26-2-xen-amd64 #1 SMP Wed Mar 10 00:29:48 UTC 2010 x86_64
postfix/main.cf:myhostname = mx.oldVPSHostName.tld
webalizer/webalizer.conf:HostName mx.oldVPSHostName.tld
Notice that your servers host name appears in a number of different files.
Edit each of the files then restart your VPS.
You may also want to edit /etc/MOD.tail (a file that is automatically appended to /etc/MOD each time the server is restarted.
To change your RDNS name
You can also change the RDNS details so that your in-addr.arpa record comes up with your own domain name.
eg.
.in-addr.arpa IN PTR mx.oldVPSHostName.tld
You can change your RDNS name in the DTC control panel on our server where you control your VPS restarts from. The 'installation' menu has a field for entering your RDNS name.
Remember that DNS changes take time. The name server is updated every 10 minutes, however your dns record also has a TTL on it which may have to expire before you can see the changes. The default TTL is 7200 seconds (2 hours).
Edit your DTC templates
DTC files live in /usr/share/dtc as per the details on this page Directory-StructureDirectoryStructure
Template files for reminder emails live in /etc/dtc
/usr/share/dtc/shared/inc/forms may also contain files that you may want to review.
Rerun the installer
If you're running DTC in your VPS then you'll need to redo the installation.
# dpkg-reconfigure dtc-postfix-courier
You will need to run the configuration wizard to update things like postfix.
# /use/share/dtc/admin/install/install
You need to rerun the installer as well.
