smtp issue

[nishnish]

greetings.

for the past week i have been unable to send emails. each time i try to send i get:

An error occurred while sending mail. The mail server responded:
5.7.1 <chris@whatever.com.au>... Relaying denied. IP name possibly forged [203.217.83.126].
Please ensure that you are using the correct identity to send and that the used authentication method is correct. Verify that you are allowed to send via this SMTP server with your current credentials from your current network.

this is only a new thing and i have been sending with the correct set up for a while.

any ideas?
