     2 Managing alias domains
       
     3 ======================
       
     4 An alias domain is an alias for a domain that was previously added with the
       
     5 subcommand :ref:`domainadd`.
       
     6 All accounts, aliases and relocated users from the domain will be also
       
     7 available in the alias domain.
       
     8 In the following is to be assumed that example.net is an alias for example.com.
       
     9 
       
    10 Postfix will not accept erroneously e-mails for unknown.user\@example.net
       
    11 and bounce them back later to the mostly faked sender.
       
    12 Postfix will immediately reject all e-mails addressed to nonexistent users.
       
    13 
       
    14 This behavior is ensured as long as you use the recommended database queries
       
    15 in your :file:`{$config_directory}/pgsql-*.cf` configuration files.

    17 aliasdomainadd
       
    18 --------------
       
    19 Syntax:
       
    20  | **vmm aliasdomainadd** *fqdn destination*
       
    21  | **vmm ada** *fqdn destination*
       
    22 
       
    23 This subcommand adds the new alias domain (*fqdn*) to the *destination*
       
    24 domain that should be aliased.
       
    25 
       
    26 Example:
       
    27 
       
    28 .. code-block:: console
       
    29 
       
    30  root@host:~# vmm aliasdomainadd example.net example.com
       
    31 
       
    32 aliasdomaindelete
       
    33 -----------------
       
    34 Syntax:
       
    35  | **vmm aliasdomaindelete** *fqdn*
       
    36  | **vmm add** *fqdn*
       
    37 
       
    38 Use this subcommand if the alias domain *fqdn* should be removed.
       
    39 
       
    40 Example:
       
    41 
       
    42 .. code-block:: console
       
    43 
       
    44  root@host:~# vmm aliasdomaindelete e.g.example.com
       
    45 
       
    46 aliasdomaininfo
       
    47 ---------------
       
    48 Syntax:
       
    49  | **vmm aliasdomaininfo** *fqdn*
       
    50  | **vmm adi** *fqdn*
       
    51 
       
    52 This subcommand shows to which domain the alias domain *fqdn* is assigned to.
       
    53 
       
    54 Example:
       
    55 
       
    56 .. code-block:: console
       
    57 
       
    58  root@host:~# vmm adi example.net
       
    59  Alias domain information
       
    60  ------------------------
       
    61          The alias domain example.net belongs to:
       
    62              * example.com
       
    63 
       
    64 aliasdomainswitch
       
    65 -----------------
       
    66 Syntax:
       
    67  | **vmm aliasdomainswitch** *fqdn destination*
       
    68  | **vmm aos** *fqdn destination*
       
    69 
       
    70 If the destination of the existing alias domain *fqdn* should be switched
       
    71 to another *destination* use this subcommand.
       
    72 
       
    73 Example:
       
    74 
       
    75 .. code-block:: console
       
    76 
       
    77  root@host:~# vmm aliasdomainswitch example.name example.org
