I am receiving this message when attempting to send an email to a craigslist job posting. I've researched this on the web and found articles that show to remove the 'require that all senders rae authenticated' in the email settings for the sender but still get the same result.

Any ideas?

Reject messages from no senders is also not checked.

Our system is Windows 2003 with Exch 2007.
