     2 Managing catch-all addresses

     3 ============================

     4 catchalladd

     5 -----------

     6 Syntax:

     7  | **vmm catchalladd** *fqdn destination ...*

     8  | **vmm caa** *fqdn destination ...*

     9 

    10 This subcommand allows to specify destination addresses for a domain, which

    11 shall receive mail addressed to unknown local-parts within that domain.

    12 Those catch-all aliases hence "catch all" mail to  any address in the domain

    13 (unless a more specific alias, mailbox or relocated entry exists).

    14 

    15 .. warning::

    16    Catch-all addresses can cause mail server flooding because spammers like

    17    to deliver mail to all possible combinations of names, e.g. to all

    18    addresses between abba\@example.org and zztop\@example.org.

    19 

    20 Example:

    21 

    22 .. code-block:: console

    23 

    24  root@host:~# vmm catchalladd example.com user@example.org

    25 

    26 .. versionadded:: 0.6.0

    27 

    28 catchalldelete

    29 --------------

    30 Syntax:

    31  | **vmm catchalldelete** *fqdn* [*destination* ...]

    32  | **vmm cad** *fqdn* [*destination* ...]

    33 

    34 With this subcommand, catch-all aliases defined for a domain can be removed,

    35 either all of them, or those *destination*\ s which were specified explicitly.

    36 

    37 Example:

    38 

    39 .. code-block:: console

    40 

    41  root@host:~# vmm catchalldelete example.com user@example.com

    42 

    43 .. versionadded:: 0.6.0

    44 

    45 .. versionchanged:: 0.6.1

    46    Accept multiple destinations.

    47 

    48 catchallinfo

    49 ------------

    50 Syntax:

    51  | **vmm catchallinfo** *fqdn*

    52  | **vmm cai** *fqdn*

    53 

    54 This subcommand displays information about catch-all aliases defined for

    55 a domain.

    56 

    57 Example:

    58 

    59 .. code-block:: console

    60 

    61  root@host:~# vmm catchallinfo example.com

    62  Catch-all information

    63  ---------------------

    64    Mail to unknown localparts in domain example.com will be sent to:

    65           * user@example.org

    66 

    67 .. versionadded:: 0.6.0
