    DISCARD returns OK terminating evaluation of its restriction class.

    Recipient validation happens *after* all the restrictions are processed.
    Make sure your spam trap addresses are valid email addresses per
    local_recipient_maps, virtual_alias_maps, virtual_mailbox_maps or
    relay_recipient_maps as appropriate.

    There is not yet any logic in Postfix to turn off recipient validation for
    discarded messages. This is a reasonable feature request to be added to a
    long list of reasonable feature requests...
