Hi there

does anybody have experience with mailserver migration and apple clients.
We have no changed the ip address of our mailserver -> we have changed the A Record from mail.xy.ch to a new IP.
Since then we've a lot of calls from clients which are unable to receive mails.

On the iPhones, the authentication option has gone!!. When the customer set its back to password it's working again.
But I had also some OS X Mail which had the right settings, but didn't work. I had to configure the account from scratch.

So it's defnitely an Apple "Problem".

Does anybody now why this is not working or why the settings are changed from the device itselfs?

Freundliche Grüsse
