Uh.... sorry Rendi! As I said: I was in a hurry, I didn't mean to direct the answer to you! It should go to Peter (I took the wrong name).
Anyway, I don't have the original OP message (I don't know why, I just don't have it), so, I answered with what I have, and based on my experience: with these directives, you can implement a "person-by-person" migration, ie: within "internal network", SMTP auth would be optional, thus allowing you to have a mixed environment (some people with auth, some people without auth). No, this won't generate the message he wants, but allows you to slowly adopt the SMTP authentication, without disrupting current users. About the "bounce" message (which would not be exactly a bounce), I would have to think more about it, but I bet there are ways of doing it.... However, I think it is better that he just send out massive email to his 200k users telling them that they should update their configuration to use SMTP authentication, and that starting X date, unauthenticated mails will be rejected, and repeat the message some times (once a week for a month, for example). That'd be simple to do, and should work.
