Ah. Hmm. That does sound like a bit of a problem. What sort of complicated certificate management? (The reason to do this is to make the move over seamless for the user of that domain, and that it how their previous host had the mail setup. Duplicating the setup means I do not have to go in and change the mail servers on every client computer, phone, and tablet, so this is desirable. But secure submission is required by the server at all times, so if that gets messed up, I've gained nothing. -- 'Never trust a ruler who puts his faith in tunnels and bunkers and escape routes.
