When setting up an email account, always use these basic settings:
Username: your full email address
Password: as setup in cPanel (See "Creating an Email Account" for more information)
Incoming server: mail.yourdomain.com.au (Port 110)
Outgoing server: mail.yourdomain.com.au (Port 25 or 26*)
* We recommend using port 26 to avoid conflicts with some Internet Service Providers (ISPs).
Our outgoing mail server requires authentication using the same settings as the incoming mail server.
