through the filter.
Centipaid supports two types of stamps.

Payment processing is paid by the recepient.
The module can also be used in conjunction with SpamAssassin to autoamtically
reject email messages with a certain spam ranking, and to be directed to pay
for postage.
Other uses include the designation of postage-requiered email accounts such
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.
