EPA Features

Operational Applicability

• Controls and manages all domain e-mail traffic - Internet inbound & outbound, intranet/LAN internal.
  
• Uniform functionality in all domain types - organizational & enterprise & ISP & ESP & personal.
  
• Uniform functionality and operation across all e-mail platforms.
  
• Scaleable to serve the needs of organizations and individuals.
  
• Accomodates all natural languages
  
• Accomodates all standard-defined code/glyph sets
  

Domain Security & Integrity

• Unauthorized Internet-incoming traffic can be denied acceptance and entrance.
  
• Unauthorized Internet-outgoing traffic can be denied transmission and exit.
  
• Unauthorized domain-internal can be denied transmission.
  
• All unauthorized traffic can be quarantined and 'safe-warehoused' for analysis.
  
• A single set of criteria can be applied to all mailboxes' traffic
  
• Any domain mailbox's e-mail facilities access can be restricted to ---
  --- SysAdmin communications only with no Internet-access.
  --- Domain-internal mailboxes only with no Internet-access.
  --- A group of domain-internal mailboxes only with no Internet-access.
  --- Internet access only.
  --- Internet-transmission-only access
  
• General-Public-Correspondence mailboxes mask internal mailbox URL's.
  
• SysAdmin can transmit e-mail to and received e-mail from all managed mailboxes.
  
• SysAdmin communuications are not filtered and classified.
  
• ISP-domain Group Managers can communicate with and filter traffic for any Group mailbox.
  
• Any number of 'malware' detectors can be daisy-chained to examine e-mails traffic.
  

User Friendly

• Easily understood and applied.
  
• Minimized required user documentation, education and support.
  
• Increased automated post-reception & pre-transmission & post-transmission e-mail processing capabilities.
  
• Send-only mailbox prevents uncontrolled e-mail response.
  
• ISP-domain SysAdminss can communicate with any leased mailbox but not permitted to filter traffic.
  
• ISP-domain Group Managers can communicate with any leased Group mailbox and filter its' traffic.
  
• Minimize System/E-Mail Administrator’s installation and operational task load.
  
• SysAdmin able to receive any internal e-mail traffic.
  
• Reduce costs of manual e-mail processing.
  

Engineering-Reduced 'Necessary and Sufficient' Functionality

• Functionality limited to filtering, classification and post-classification process selection
  
• Accurate reliable filtering tests yield unambigous, mutually-exclusive results.
  
• Every mailbox has owner-specified definition of filtering criteria.
  
• Traffic processing records and filtering criteria history provide process accountability.
  

Software Engineering

• Maximized product life span due to absolute minimum dependency on host-system hardware/software platforms' operational specifics with ---
  --- Tight integration into OSI Layer precisely at the Layer 6-to-Layer 7 border.
  --- Layer 6 ioutput/input interception and processing that is transparent to Layer 6 MTA.
  --- No interactions or interfaces with Layer 7 application and e-mail clients.
  
• Maximized component reuseability of all software, education and documentation for product extensions.>
  
• Open-ended for additional parallel and daisy-chained functionaility supplied by other processes.
  
• Standardized functional foundation for third-party product extensions and enhancements.
  
• Unobtrusive integration into legacy, current, and future e-mail software.
