This is easy - it's just a matter of creating an account in your e-mail program. We'll describe the process for Microsoft Outlook; it will be similar for other e-mail programs.
What you need to know
Before starting, you need to know:
- The e-mail user name: This is usually the bit in front of the "@" in your e-mail address. For instance, if your e-mail address is joe.bloggs@example.com, the username is joe.bloggs.
- The password
- The incoming mail server: This is "mail." followed by the domain name - e.g. mail.example.com.
You also need to know the outgoing mail server. This will be the same for all your e-mail accounts. In Outlook, to see your e-mail accounts, go to the Tools menu and choose "E-Mail Accounts". Then click "View or change existing accounts". This shows you all your existing accounts (there might be only one). Select any of them and click the "Change..." button. This displays a properties window for that account. Make a note of the outgoing mail server (click picture for larger version):

Test the settings in Webmail
This is an optional step that ensures the new mailbox is active, and that you've got the right user name and password.
First, send a test message to the e-mail address. We'll now check the new mailbox using your Web browser rather than your e-mail program. The Webmail address is "webmail." followed by your domain name - e.g. webmail.example.com. Go to this page in your Web browser and log in using the user name and password from above (click picture for larger version):

If you can't log in, it means either the user name or password is wrong, so try again, and if it still doesn't work, get the correct details from somebody who knows them.
If it does work, you should see the test message sitting there in the mailbox (click picture for larger version):

Keep it there and log out of Webmail. Now you're ready to change the settings in Outlook.
Changing the settings
In Outlook, go to the Tools menu and choose "E-Mail Accounts". Then click "Add a new e-mail account". Choose "POP3" and you'll get a blank page to fill in (click picture for larger version):

Fill in the form as follows:
- Your Name: Your real name
- E-mail Address: The e-mail address you'd like people to know
- User Name, Password, Incoming Mail Server, Outgoing Mail Server: The settings you noted earlier

Save the settings and you're done!
Testing
Do a "Send and Receive" in Outlook, and make sure that you receive the test e-mail you received earlier. Also send a new message from this account, to yourself, and make sure you receive it with the correct name and e-mail address.
