Regular Expressions for Internet Mail draft-01 has been updated. There
is a brief change log in Appendix B, which is reprinted below. I/we look
forward to discussing and hopefully getting this dispatched.
Appendix B. Change Log
The document status is now marked as Informational instead of Best
Current Practice (although it seems that it could go either way).
The authors decided to focus on "modern" ASCII-only email identifiers
first and to get those right before tackling Unicode email
identifiers and "obsolete" ABNF productions. This draft-01 preserves
the main text of draft-00 rather than remove potentially useful text.
Deliverable and modern email addresses, and modern Message-IDs, have
been addressed. The Unicode work remains unfinished for now;
"obsolete" ABNF productions (which are still useful for archival
applications) will also be addressed in future drafts.
The authors decided to write one set of regular expressions in one
dialect (namely, PCRE/PCRE2) before tackling others (e.g.,

Title: Regular Expressions for Internet Mail
Document date: 2016-10-30
Group: Individual Submission
Internet Mail identifiers are used ubiquitously throughout computing
systems as building blocks of online identity. Unfortunately,
incomplete understandings of the syntaxes of these identifiers has
led to interoperability problems and poor user experiences. Many
users use specific characters in their addresses that are not
properly accepted on various systems. This document prescribes
normative regular expression (regex) patterns for all Internet-
connected systems to use when validating or parsing Internet Mail
identifiers, with special attention to regular expressions that work
with popular languages and platforms.
