match local recipients in virtual_alias_maps

  • 772

I want to redirect all local mail by specifying an address in virtual_alias_maps file.

It is possible to match recipients with regexp, but it's too complex. They can be:

  • no domain (root etc.)
  • root@localhost
  • root@myserver

Here: http://forums.debian.net/viewtopic.php?f=16&t=107671 they try to match /.+@.+\.localdomain/ , which of course doesn't work.

Postfix already has $mydestination config parameter. Can I match with it somehow?

Upd: tried local_transport = virtual: , but virtual cannot forward.

Perhaps a global .forward file will help?

    Don't use virtual_alias_maps, use alias_maps instead.

    • Parameter virtual_alias_maps match all address classes
    • Parameter alias_maps match only local address class i.e. address defined in mydestination parameter

    See Address Class README for more information.

    So, the parameter of alias_maps would become

    #main.cf
alias_maps = pcre:/etc/postfix/catch-my-local

#/etc/postfix/catch-my-local
/.+/   [email protected]

    Alternatively, you can put forward_path = /etc/postfix/global-forward in main.cf. Basically, you override the path of .forward file for EVERY user.

    In /etc/postfix/global-forward just put

    [email protected]

    No need to specify the left side mapping.

    Credit to OP for this workaround.
