NDRs Only, No Outbound External E-mail

I have a Small Business Server 2003 SP2 and Exchange has SP2. Every email sent from Outlook immediately results in the following NDR. Same result for OWA.

The recipient could not be processed because it would violate the security policy in force
<myserver.local #5.7.0 smtp;530 5.7.0 Authentication required>

No changes to to Exchange in months. We are not using a smart host. I am
told the domain hosting company did make some unknown change about the same time
this problem began. I do not understand how this could effect us though.

Is your Exchange environment setup to use the SMTP connector to send out email?

Looks like the domain hosting company has made some changes in the policy which is not allowing users from your domain to get authenticated against the security settings that they would have configured to authenticate incoming requests from your domain and then allow those mails to pass through to different domains.

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

1. Thank you, yes the SMTP Connector is setup.
2. I will contact the hositng company in a day or so.
3. Thanks, I will check to see if the solution in the first html link applies.  The circumstances are very similar.

The link from mwecomputers did not help.  Outlook 2000 does not appear to have the authentication methods referenced in the link.
Have not a chance to speak to the hosting company however I question their involvement because the NDR appears literally one and one half seconds after you click send.  I can not believe the response could come from the hosting that fast.
FYI, adding a Smart Host changes nothing.
Anyone care to scratch their head somemore?

PROBLEM SOLVED
The ISP changed the dymanic ip address and the Smart Host being used by the SBS SMTP Connector now requires authentication.  Deleted the SBS SMTP Connector, used the Default SMTP Virtual Connector with a new Smart Host with the proper credentials.
Thanks to everyone for their suggestions!
