OSX Server 5.1.x: iOS 9.x / SMIME Support

[d4gli]

Hi,

we're testing a move from exchange 2016 to OSX Server 5.1 to reduce monthly lic. coasts. When we used FreeBSD with Davical and usual Postfix setup or Exchange - we had additional option in the mail menu on iOS to enable SMIME signature/crypto.

If I setup a new account on iOS, there's no option to enable this. If I setup this account as a usual IMAP account, I'm able to activate this one...

Any hint on this?

Thanks.

Which email system are you setting up with your new Sever?

Part me, what do you mean?
El Cap. OSX Server 5.1 with it's postfix... iOS with it's native mail client

This screen is missing on iOs when added as OSX Server account: https://support.apple.com/library/c.../iphone6-ios8-settings-encrypt_by_default.png

When I add this as an usual IMAP account, everything is fine
