Hi, we have a situation where two different companies both have SBS 2007 servers.  

When Company B tries to send to Company A, they get a bounce back (see attached)

Mail in the opposite direction works fine.  

We've disabled spam filters on Company A, and don't see any obvious cause of this problem.  Mail flow was fine up until recently, and no settings have been changed on either server in the last few months, and this problem developed last week.  We even looked at Windows Updates, and don't see any that came down at roughly the time this started.

Thanks for any advice

It sounds like the Anonymous Users Access has been removed from Company A's Windows SBS Internet Receive Connector.

That will cause all manner of mail-flow issues including not receiving any mail!

Thanks for the response

I checked and Anonymous access is still allowed.

Under Authentication, only TLS is checked.  Is this correct?

Any other thoughts?

TLS and Anonymous is all that should be enabled on the default Receive Connector.

Is there another connector configured just for Company B?  If so, the auth / permission groups might not be configured properly.

No, but this is odd -- after your last email, I created a connector and set it up just for them.  On that one, I matched the auth/permissions settings exactly to the default one, and now mail is flowing fine for everybody.

I'm not sure why or how this could have happened.  Any thoughts?

Remotely no!  Please run the following from the Exchange Management Shell and post the output for review (you can hide the incriminating info if you like):
