iCloud email account can not send emails since update on 10.11

I updated my macbook pro 2012 to OS X 10.11. My mail account vie iCloud could since then not send out any emails. The email server settings were lost completely!! I searched the support dtabsa for the proper mailserver settings, but it seems this informations are outdated and inaccurate.

Could any body give me the complete settings for the outgoing email server for iCloud?

Gx
