Alias features

  • supports multiple destinations per e-mail alias

  • destinations can be deleted separately

  • respects Postfix’ virtual_alias_expansion_limit on creation

  • destinations can be interpolated using the original address’ local-part and domain, allowing aliases to have different meaning in alias domains, e.g. with the following defined in example.org:

    postmaster@example.org  →  postmaster+%d@admin.example.org

    If example.com is an alias domain of example.org, the alias will become:

    postmaster@example.org  →  postmaster+example.org@admin.example.org
    postmaster@example.com  →  postmaster+example.com@admin.example.org
