The Mailbox Reputation Network
Summary
The mailbox reputation network (MRN) is a hybrid email sender reputation framework and global-scale peer-to-peer social network publishing system.
It's primary application is in maintaining a distributed trust network for blocking or prioritizing email deliveries in the context of an authenticated sender scheme.
A secondary application is in maintaining a unified intersite global social network relating user profiles for disparate user communites accross the web in a uniform way.
Features
- Base network operates over the domain name system (DNS)
- Optional extensions via URI protocol schemes and XML
- Fully decentralized administration
- Supports peer and sponsorship relations between individual mailboxes
- Supports peer and sponsorship relations between whole domains
- Supports principal-agent reputation equivalences
- Supports mailbox profile schema extensions via XML
- Supports relation assertion schema extensions via XML
- Compatible with all sender authentication schemes (SPF, DMP, RMX, DomainKeys, etc)
- A free, open standard - no (known) patents or royalties
- Online specification, examples and utilities
- Supports delegation
- Provision of a fallback domain for ease of adoption
Directed reputation graphs
MRN maintains a graph with the following relation types:
- Principal-Sponsor: Separate reputations, unilateral peer relation - sponsor is responsible for the behaviour of the principal. Principal not responsible for sponsor.
- Principal-Peer: Separate reputations, mutual peer relations - each reflect on the other
- Agent-Principal: Single reputation, unlateral principal relation - agent acts with principal's reputation
Mutual agent-principal relations are not permitted.
Policy engines, application heuristics and reputation scoring
MRN is scoring-system independent. It is intended to provide a corpus of social network relationship data for subsequent use by heuristic/scoring policy engines.
Such a scoring engine sits between the application filter and the MRN network as follows:
Application filter <=DNS=> Scoring Engine <=DNS=> MRN Network
Get involved
If you wish to participate in developing/testing of the Mailbox Reputation Network, or are simply curious, the first step is to subscribe to the mailing list.
To subscribe to the mailing list, send a mail with 'subscribe' in the subject to:

To get started publishing MRN records, enter a domain name or email address (mailbox) of yours here:
We also need participants who are willing to:
- Discuss and contribute to the specification
- Develop policy engines
- Sponsor new entrants
- Search/spider the network, provide portals etc
- Develop mailserver filters
- Publish mailbox-level records, eg ISP's and Social Networkng sites
- Encourage others to join (eg link to this page!)
