Currently, the alias domain can only be set by selecting:
'Custom Email Server' in the settings.
This does not make sense for users of pre-configured databases who
just want to use the default server with their own domain.
We move the domain to its own setting to prevent confusion.
As people are not always aware they can just set a domain without
configuring a server.
