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
Add 'mail.alias.domain' information on alias model. Aliases do not use global
configuration parameters anymore. Instead they are linked to an alias domain
e.g. 'sales' linked to 'mycompany.com' alias domain: 'sales@mycompany.com'.
It is now considered as a different alias compared to 'sales@mycompany.in'
which has the same alias_name but a different alias domain.
Constraints and checks are added, as
* uniqueness of aliases is now checked inside a given domain;
* an alias name must not clash with its domain bounce or catchall;
* a combination of (alias_name, alias_domain_id) must be unique;
Crm multi-company environment is also updated to match the new alias domain
behavior.
