Some weeks ago my mail server was put onto another machine with a different IP.
After a few days most of the eMail traffic was redirected successfully to the new mail server.

However there are still some eMails which are directed to the old mail server (which is still running).

Why ?

Is there a way to re-inforce the DNS re-location? In other words:
Is there a way to force a re-propagation of the Mail-Server DNS change information all
over the world wide Mail server structure?
