OS X Server account in iOS9 is missing delegates and aliases

I am running OS X Server 10.11.3, mixed home and business. On the server there are multiple accounts and I share calendars with other users. On the server several domains are hosted, of each one I have an e-mail account.

When I use my Mac Pro client (El Capitan 10.11.3):

- In Mail I can specify all my mail aliases to send mail from

- In Calendar I can see all calendars I am authorized to see.

Before, it was a lot of work to make sure all the accounts of the services were werking well (Snow Leopard XServe) but now I found the option to create an OS X Server Account on my iPhone (5S iOS 9.2). This made life much easier. But:

- In iOS Mail I can only see the first e-mail account that is specified in my list of e-mail addresses on the server, and the others are not shown/selectable in the "from" field when I write a mail on my iPhone

- On my iPhone I can only see my own calendars.

The problems also showed in earlier versions of El Capitan and iOS9.

Am I missing something? Any help appreciated.
