Yes it is possible.
On your phone under Email Settings there should be somewhere where you can add a new account.
You will probably have to name the account so just call it Virgin or Email or something...
Under email address type your VM email address.
There should be somewhere on your phone which lets you change the Connection Type...
Change this to POP3.
Change the Incoming Server to pop.ntlworld.com
Username is just your email address without the @ntlworld.com and then type your password in.
Hope this helps mate.
