 Upon creating a domain on People, the same domain is created on dimail and will undergo a series of checks. When all checks have passed, the domain is considered valid and mailboxes can be created on it.

 ### Users
 
 The ones issuing requests. Dimail users will reflect domains owners and administrators on People, for logging purposes and to allow direct use of dimail, if desired. User reconciliation is made on user uuid provided by ProConnect.
