Alan Shipman, Editor, British Standards Institution (BSI), published a paper on RMail Registered E-mail™ Services and Evidence issues within the United Kingdom Legal System, opining the Registered Email™ services comply with and map to the BSI standard: BS 10008:2014 Evidential Weight and Legal Admissibility.

Locke Lord Bissell and Liddell LLP published a detailed legal analysis (available from RPost upon request) that maps the Registered Email™ technology to electronic commerce law and opines that the Registered Email technology satisfies seven key legal principles important to yield a legally valid and court admissible piece of evidence that has high evidential weight. In brief, the legal analysis opines that the Registered Email technology:

  • DELIVERY PROOF : Provides a record of sending and receiving in accordance with the Uniform Electronic Transactions Act (UETA) by recording the recipient’s server’s receipt;
  • CONTENT PROOF : Uses cryptographic techniques to mathematically associate and preserve as tamper-detectable the contents of email and their attachments so as to satisfy process requirements designed under UETA, the Electronic Signatures in Global and National Commerce Act (ESIGN), and in evidence law to establish evidence of content;
  • OFFICIAL TIME STAMP : Links to a trusted and objective time source providing essential and credible evidence in disputes in which the time an email was sent or received is material to the case;
  • ADMISSIBLE EVIDENCE : Produces records that are court-admissible as to their fact of delivery, as to their legal time of delivery and as to authenticity of content;
  • FUNCTIONAL EQUIVALENCE : Serves, under the Uniform Electronic Transactions Act (UETA) and the Electronic Signatures in Global and National Commerce Act (ESIGN), as the functional equivalent of paper mail, to be used in lieu of certified mail, registered mail, return receipt mail, private express mail services and similar types of paper mail services;
  • ELECTRONIC ORIGINAL : Provides a true electronic original of the message content, message attachments, and transmission meta-data including the delivery audit trail; and
  • CONSENT : Records consent, as under electronic law the recipient of the electronic transmission must have consented to the use of electronic format as opposed to paper; with a record of the recipient’s consent retained as a reproducible legal record to prove consent if challenged.

Requirements: Legal & Compliance

RMail® Registered Email™ e-delivery proof meets the ESIGN, UETA, eIDAS, PEC, ETSI Registered Electronic Mail Standard, BSI Standard BS 10008:2014 Evidential Weight and Legal Admissibility, and other legal e-delivery standards internationally. RMail email encryption provides simple to use and automated privacy compliance for HIPAA, GDPR, and other state and country regulations protecting personal private information, returning auditable proof of privacy compliance in the form of a Registered Receipt™ email record for each message sent.
