Autodiscover NS8 and sogo

NethServer Version: NS8
Module: Sogo

Hi,

How must i setup the autodiscovery with NS8 and Sogo
What i’ve found is to add a CNAME to my DNS management, but must this be linked to the Sogo FQDN ?
my mail server FQDN is

mail.mydomain.nl

my Sogo server FQDN is

sogo.mydomain.nl
