It will work, but two things make it hard to set up an @riverland.net.au email account on a phone or i-device:

• The phone may try to guess the account settings. This generally fails. It's quicker to choose “enter settings manually” instead of waiting for the auto-detect to try and fail.

• The phone may guess that it's an IMAP account. Accounts @riverland.net.au are POP3, not IMAP. Be sure to set it to POP3.

Apart from those, use the generic account settings.
