+======================
+Managing alias domains
+======================
+An alias domain is an alias for a domain that was previously added with the
+subcommand :ref:`domainadd`.
+All accounts, aliases and relocated users from the domain will be also
+available in the alias domain.
+In the following is to be assumed that example.net is an alias for example.com.
+
+Postfix will not accept erroneously e-mails for unknown.user\@example.net
+and bounce them back later to the mostly faked sender.
+Postfix will immediately reject all e-mails addressed to nonexistent users.
+
+This behavior is ensured as long as you use the recommended database queries
+in your :file:`{$config_directory}/pgsql-*.cf` configuration files.
+
+aliasdomainadd
+--------------
+Syntax:
+ | **vmm aliasdomainadd** *fqdn destination*
+ | **vmm ada** *fqdn destination*
+
+This subcommand adds the new alias domain (*fqdn*) to the *destination*
+domain that should be aliased.
+
+Example:
+
+.. code-block:: console
+
+ root@host:~# vmm aliasdomainadd example.net example.com
+
+aliasdomaindelete
+-----------------
+Syntax:
+ | **vmm aliasdomaindelete** *fqdn*
+ | **vmm add** *fqdn*
+
+Use this subcommand if the alias domain *fqdn* should be removed.
+
+Example:
+
+.. code-block:: console
+
+ root@host:~# vmm aliasdomaindelete e.g.example.com
+
+aliasdomaininfo
+---------------
+Syntax:
+ | **vmm aliasdomaininfo** *fqdn*
+ | **vmm adi** *fqdn*
+
+This subcommand shows to which domain the alias domain *fqdn* is assigned to.
+
+Example:
+
+.. code-block:: console
+
+ root@host:~# vmm adi example.net
+ Alias domain information
+ ------------------------
+         The alias domain example.net belongs to:
+             * example.com
+
+aliasdomainswitch
+-----------------
+Syntax:
+ | **vmm aliasdomainswitch** *fqdn destination*
+ | **vmm aos** *fqdn destination*
+
+If the destination of the existing alias domain *fqdn* should be switched
+to another *destination* use this subcommand.
+
+Example:
+
+.. code-block:: console
+
+ root@host:~# vmm aliasdomainswitch example.name example.org
