You can bypass the Nokia Messaging service by selecting Decline of Terms and Service during Email setup. 

Your device such as the Nokia E72 which is a built-in email client device, comes bundled with a lifetime subscription to Nokia Messaging service; hence, during the configuration for email service, if you don't want to use Nokia Messaging to get push delivery of your email, then do not accept the service terms - this will allow you to set up direct-access email.
