Mechanism to sync mail accounts between Mac and iPhone Is there a way for me to create an account using my Mac's Mail app and have the account sync over to my iPhone or vice versa? I have iCloud setup on both my Mac and iPhone, but I don't see the accounts added on one device syncing over to the other.
No.

(if what you want is a way to configure an account once on a device and have the configuration automagically transferred to other devices.)
