Yup, I have gone though every single connectors advanced tabs, used winroute and remonitor to get rid of any stale connectors. I've got a call open with MS. We'll see what they come up with.

Question
Exchange Internal Email 5.7.0 Errors
I'm having a rather strange error with one of my internal Exchange servers believing the messages it sends need to be encrypted with TLS. These are all inter-company emails.
Exchange 2003 SP2
Event log:
A non-delivery report with a status code of 5.7.0 was generated for recipient rfc822;
System Reply Admin:
The recipient could not be processed because it would violate the security policy in force
<server-ex01.domain #5.7.0 smtp;530 5.7.0 Must issue a STARTTLS command first>
We use a hub and spoke setup where all messages(that are not local delivery) funnel though a central site before being passed off to their internal destination. On the bright side this is a sort of backup link so not many messages flow though this connector.
I've telneted into this server and STARTTLS is not enabled in the "ehlo" reply. I've checked though ESM and do not see TLS enabled anywhere in the "SMTP virtual Server."
Any suggestions or places to look?
