When the full account name is composed, this name (address) is passed to the Router.
- If the Router reports an error, the client is not authenticated and an error message is returned to the client application. An error is usually the Unknown user error, but it can be any error that Router or modules can generate when routing an address.
- If the Router has successfully routed the address, but the address is not routed to the Local Delivery module, the client is not authenticated and an error message is returned to the client application. This happens if a user has specified a mailing list name, not an account name, or if the specified name is rerouted to some other host (via SMTP, for example).
- If the Router routed the address to some Account in some local Domain, that Account is opened, and the Account passwords are checked.
This means that all routing applied to E-mail and Signal addresses is also applied to the account names specified with mailer applications.
- The Account john has a john_smith alias;
- all E-mail messages and Signals addressed to john_smith will be delivered to the Account john;
- the user can specify either john or john_smith as the "account name" setting in his client applications - in both cases the Account john will be opened when those applications connect to the Server.
- The Account john has been moved from the main domain company.com to the domain client1.com, and it was renamed in j.smith. The administrator has created a Router record:
- <John> = email@example.com;
- all E-mails and Signals addressed to firstname.lastname@example.org will be sent to the Account j.smith in the client1.com Domain;
the user can still specify just john as the "account name" setting, and the same company.com "server" setting in his client application - but the Server will open the Account j.smith in the client1.com Domain.
do not create any Router record that redirects the Postmaster Account in the Main Domain. You will not be able to administer the Server, unless the postmaster account is redirected to an Account that has the Master access right.
If you want the Postmaster E-mails and Signals to be directed to some other user, do not use the Router, but use the postmaster Account Rules instead.
