The key words "MUST", "MUST NOT", "SHOULD", "SHOULD NOT", and "MAY" in this document are to be interpreted as defined in "Key words for use in RFCs to Indicate Requirement Levels" [KEYWORDS]. Abstract This document describes the functional specification and the definition of the ENUM NAPTR record, for IFax service. IFax is "Facsimile using Internet Mail". For this use, the DNS returns the email address of the referenced IFax system. This mechanism allows email-based fax communication to use telephone numbers, rather than requiring that the sender already know the recipient email address. 1. Functional Specification An IFax client makes an [ENUMbis] DNS query, using the target system's telephone number. The returned NAPTR record specifies an email address that is to be used for reaching the target system. The email address is then used in accordance with "Simple Mode of Facsimile using Internet Mail" [RFC2305] or "Extended Facsimile using Internet Mail" [RFC2532]. "Full Mode Fax Profile for Internet Mail" is applied when it is approved as an Internet standards-track specification. 2. Definition of NAPTR record 2.1 Service Name Service Name = "ifax" The scope of this service is facsimile using Internet mail. It includes "Simple Mode of Facsimile using Internet Mail" and "Extended Facsimile using Internet Mail". "Full Mode Fax Profile for Internet Mail" is applied when it is approved as an Internet standards-track specification. 2.2 Type Type = "ifax" 2.3 Subtype Subtype = "mailto" 2.4 URI Scheme Scheme = "mailto" The URI Scheme is "mailto" because facsimile using Internet Mail is a profile for standard Internet mail and uses standard Internet mail addressing. 2.5 Example $ORIGIN 184.108.40.206.220.127.116.11.6.4.e164.arpa IN NAPTR 10 10 "u" "E2U+ifax:mailto" "!^.*$!mailto:email@example.com!" 2.6 Intended usage COMMON 3 Security Consideration The Security Considerations section of [RFC2305] and [RFC2532] applies to this document. In addition, note that DNS records are public. Therefore the mapping between a telephone number and a specific email address is public. 4. REFERENCES [ENUMbis] Falstrom, P., M.
