Mail::Audit::Centipaid is an email filter that is used to
detect the precence of electronic postage. Once detected, the postage is checked
against the receipt server of Centipaid.com to insure that the the proper
payment has been made.
Centipaid.com can process electronic postage as low as $0.001. The idea of
this filter came about as another method to control the growing problem of SPAM,
which was proposed by the Adaptive Mail Delivery Protocol (AMDP). Please refer
to amdpmail.com for more info.
Mail::Audit::Centipaid can be used by individuals or companies to designate
one or more email accounts SPAM free. This is done by installing a .forward for
these accounts, and use the enclosed centifilter.pl program to filter out mail
that does not contain valid postage. Only paid email will be allowed through the
filter.
