PURPOSE
Allow alias domains to be multiple, notably to be used in a multi company
environment where each company has its own alias domain.
SPECIFICATIONS
Update settings to configure your company's current alias domain instead
of the global 'alias.catchall.domain' configuration parameter. As domain
configuration is globally done per company, this is now a related on the
company. Advanced configuration and management can still be done manually
in settings.
Field 'external_email_server_default' triggering display of mail configuration
is moved to mail. It is defined in 'base_setup' but used only in mail hence
moving the field to be coherent.
