Exchange Server 2007 Rejecting email sent to group

We added a new domain to our Exchange server. Users receive email both internally and externally. However, we created a group for orders, added exchange accounts to the group and assigned the group an email address (e.g. orders@domain.com).

When sending test emails to the orders group we received the following error:


Received-SPF: None (xxxxxxxExc.xxxxxxxxxxxx.local:
 dbrockstedt@cpak.com does not designate permitted sender hosts)


When we googled this, it pertained to the Sender ID function of the Anti-Spam. Just for testing purposes we disabled the Sender ID function and attempted the test email again.

Received message : "Your message wasn't delivered because of security policies. Microsoft Exchange will not try to redeliver this message for you. Please provide the following diagnostic text to your system administrator."

#< #5.7.1 smtp;550 5.7.1 RESOLVER.RST.AuthRequired; authentication required> #SMTP#

This only occurs when sending to the group email.

Thanks,

David
