wrong FQDN

[mutation]

Hello I have a server setup but mail helo reports the fqdn as ubuntu not proper domain name. It is set properly under system > general as well as mail > general.  how/where do I change this to be a proper FQDN?

running zentyal version 2.0.23
zarafa for mail

Take in account that this is the full qualified hostname of the _client_ connecting to the server, not of the server itself. The fqdn must have a domain, a hostname without domian will be reject.

You can also use submission port (587) which does not have this check. This port is intended to be used by clients from local networks.
