Error ox800CCC78

I was able to send messages via Microsoft Mail yesterday, but today it's
giving me an error.

The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was '(e-mail address removed)'. Subject 'Re:
deb's computer', Account: 'pop.iinet.net.au', Server: 'mail.iinet.net.au',
Protocol: SMTP, Server Response: '530 Authentication required', Port: 25,
Secure(SSL): No, Server Error: 530, Error Number: 0x800CCC78

Make sure you have send authentication enabled.
Go to Tools, Accounts, select that account, Properties, Servers.
The box for "My server requires authentication" must be checked.
