	as the ones used for consulting, support, business to business, etc..

    DESCRIPTION

	This filter is intended to be called by MTAs prior to mail delivery
    to determine if the message contains a valid email postage obtained
    from centipaid.  If the message contains the stamp receipt and it is
    acknowledged by centipaid as being valid for the recipient account, then
    it is accepted, otherwise a custom reply is sent to the sender with
    instructions on how to pay for postage, and a properly formatted url.
