Mediation systems and methods for restricted access item distribution are disclosed. In an embodiment, a method for facilitating payment from a user device for a restricted access item hosted by a host system is disclosed. In another embodiment, a system for facilitating payment from a user device to for a restricted access item hosted by a host system is disclosed. In another embodiment, a method for providing a mediated marketplace service is disclosed.

Mediation system and method for restricted access item distribution

Embodiments are directed towards detecting and reporting use by a domain of a message authentication mechanism, such as DomainKeys (DK), and/or DomainKeys Identified Mail (DKIM), and enabling subsequent blocking of messages based, in part, on its usage. When a message is received by an inbound message server, a message source is determined for the message. In one embodiment, the message source is a domain name associated with the sender of the message. Statistics are recorded about the message, including the message source, whether the message is suspect, includes a forged source identifier, employs DK/DKIM message authentication, and the like. The reports may then be sent to various message sources to enable them to determine the extent of use of DK/DKIM message authentication, and to selectively block, re-direct, or forward the messages based, in part, on the use of DK/DKIM message authentication mechanism.

Reporting on spoofed e-mail

A method and system is directed to providing policies for handling authenticated messages, such as email, and the like, by combining Public Key encryption and the Internet Domain Name System (the 'DNS'). The policies include system, user, statistics, new domain, unverified domain, and third party. A domain owner may validate that an email originates from an authorized sender within their domain by using a private key component to digitally sign email outbound from its domain. Employing a public key component, along with a selector, an email recipient may check the validity of the signature, and thus determine that the email originated from a sender authorized by the domain owner. In one embodiment, the public key component used to verify an email signature may be 'advertised' or otherwise made available via a TXT record in the DNS.
