Edit Domain

we installed our Univention Server with a .local Domain, but now we have the problem with open-xchange, that oxguard Emails insert the local link to external Users…

we have a A-Record from a Puplic DNS Server to the Puplic IP from the Univention, how we can change the .local Domain to our Puplic Domain ?

Changing the domain name is not recommended. Mr Bunkus did answer a question like this rather thoroughly, so I just link it here: [url]Impacts of Changing ONLY a UCS Domain Name]
