I'm trying to setup sendmail (thru Webmin), to route email to our Exchange 2010 server. I've setup the forwarding as:

mail.mydomain.com:2555

When I try to send email from sendmail I get:

530 5.7.1 Client was not authenticated

The transport hub on Exchange has the IP address of my centos box and anonymous access is setup.

I'm assuming this is because the from name does not have an account on Exchange 2010 or AD. Is there a way to spoof this or will I need to use a real AD acccount on the sendmail?
