Done.

I have observed the fact that the convention is becoming less common; we can
lament it (see below) but it will remain a fact.

That's reasonable.  Done.

I don't think that's reasonable for something like this.  RFC's are published
in english.  Protocol header names are in english.  The assigned numbers RFC
is in english.  POSTMASTER is in english.  I think that if someone wants to
address the non-english language problem that this would be a good thing, but
that's a separate document and I see no need to mention it here.

I appreciate your confidence in this document, but it's not an RFC yet.  I
am reluctant to do as you suggest since it would require making up addresses
to be the targets of the well known addresses, or using real addresses that
would ultimately be bombarded by the newbies you keep talking about.  (Not
to mention that Sendmail is not the only mail transport in town and not all
newbies will recognize an aliases file or be able to interpret one.)

Stan beat you to this suggestion, but thanks just the same.

          Standard Electronic Mail Addresses For Internet Operations


   Status of this Memo

      This document is an Internet-Draft.  Internet-Drafts are working
      documents of the Internet Engineering Task Force (IETF), its areas,
      and its working groups.  Note that other groups may also distribute
      working documents as Internet-Drafts.

      Internet-Drafts are draft documents valid for a maximum of six months
      and may be updated, replaced, or obsoleted by other documents at any
      time.  It is inappropriate to use Internet-Drafts as reference
      material or to cite them other than as ``work in progress.''

   Abstract

      This draft enumerates and describes standard electronic mail
      addresses to be used when contacting the operations personnel of an
      arbitrary domain.

      As an operational standard, the recommendations herein pertain to
      vendors only inasmuch as their end user documentation should
      recommend that these mail addresses be aliased to appropriate end
      user personnel.

      This document should be advanced as a recommended standard, since
      some of the behaviour it advocates is not prevalent enough to be
      called the ``best current practice.''

   INTERNET-DRAFT                  STD ADDR                        May 1996


   1 - Rationale and Scope

   1.1. Several previous RFC documents have specified electronic mail
   addresses to be used when reaching the operators of the new service; for
   example, [RFC822 6.3, C.6] requires the presence of a
   <[email protected]> address on all hosts that have an SMTP server.

   1.2. Other protocols have defacto standards for well known addresses,
   such as <[email protected]> for NNTP (see [RFC977]), and <[email protected]>
   for HTTP (see [HTTP]).

   1.3. Defacto standards also exist for well known addresses which have
   nothing to do with a particular protocol, e.g., <[email protected]> and
   <[email protected]>.

   1.4. The purpose of this draft is to collect all of these well known
   addresses in one place, add a few new ones, and ultimately recommend
   that IANA carry these addresses in future editions of its Defined
   Numbers periodical.

   2 - Definitions and Invariants

   2.1. The scope of a well known mail address is its domain name.  Thus,
   the mail exchangers (see [RFC974]) for a domain must handle well known
   addresses even though some of these addresses might pertain to services
   not offered by the mail exchanger hosts.  So, for example, if an NNTP
   server advertises the organization's top level domain in ``Path:''
   headers (see [RFC977]), the mail exchangers for that top level domain
   must accept mail to <[email protected]> even if the mail exchanger hosts do
   not serve the NNTP protocol.

   2.2. A host is not required to run its own SMTP server, but every host
   that implements a protocol covered by a well known mail address should
   have an MX RRset (see [RFC974]) and the mail exchangers specified by
   this RRset should recognize this host's domain name as ``local'' for the
   purpose of accepting mail bound for a well known address.  Note that
   this is true even if the advertised domain name is not the same as the
   host's domain name; for example, if an NNTP server's host name is
   DATA.RAMONA.VIX.COM yet it advertises the domain name VIX.COM in its
   ``Path:'' headers, then mail must be deliverable to both
   <[email protected]> and <[email protected]OM>.

   INTERNET-DRAFT                  STD ADDR                        May 1996


   2.3. For well known addresses that are not related to protocols, only
   the organization's top level domain name need be valid.  For example, if
   an Internet service provider's domain name is NETCOM.COM, then the
   <[email protected]> address must be deliverable, even though the
   customers whose activity generates complaints use hosts with more
   specific domain names like SHELL1.NETCOM.COM.

   2.4. Well known addresses ought to be recognized independent of
   character case.  For example, POSTMASTER, postmaster, Postmaster,
   PostMaster, and even PoStMaStEr should all be deliverable and should all
   be delivered to the same mailbox.

   3 - Well Known Addresses

   3.1. Protocol Related Addresses

      Address      Protocol   Standard(s)
      --------------------------------------------------------
      postmaster   SMTP       [RFC821], [RFC822]
      hostmaster   DNS        [RFC1033], [RFC1034], [RFC1035]
      usenet       NNTP       [RFC977]
      webmaster    HTTP       [HTTP]
      uucp         UUCP       [RFC976]


   3.2. Protocol Independent Addresses

      Address   Operations Area      Example Usage
      --------------------------------------------------------------
      abuse     Customer Relations   Inappropriate public behaviour
      noc       Network Operations   Network infrastructure problem
      trouble   Network Operations   Synonym for ``noc''
      support   Customer Support     Product or service not working

   4 - Other Well Known Addresses

   4.1. Many mailing lists have an administrative address to which add/drop
   requests and other metaqueries can be sent.  For a mailing list whose
   submission address is <[email protected]>, the usual administrative address is
   <[email protected]>.  With the advent of list management software such
   as MajorDomo, this convention is becoming less common and its absence
   for any given mailing list should be treated as a standards violation.
   Make sure that your lists each have a *-REQUEST address and complain to
   remote POSTMASTERs when you discover remote lists without *-REQUEST
   addresses.

   4.2. Several Internet Registries implement mailing lists for Autonomous
   System contacts.  So, for example, mail sent to <[email protected]> will at
   the time of this writing reach the technical contact for Autonomous
   System 3557 in the BGP4 (see [RFC1654], [RFC1655] and [RFC1656]).  Not
   all Autonomous Systems are registered with all registries, however, and
   so undeliverable addresses under this scheme should be treated as an
   inconvenience rather than as an error or a standards violation.

   4.3. In DNS (see [RFC1033], [RFC1034] and [RFC1035]), the Start Of
   Authority record (SOA RR) has a field for specifying the mail address of
   the zone's administrator.  This field should be a simple word without
   metacharacters (such as ``%'' or ``!'' or ``::''), and a transport level
   alias should be used on the relevant mail exchanger hosts to direct zone
   administration mail to the appropriate mailbox.  For simplicity and
   regularity, it is hereby recommended that the well known address
   HOSTMASTER always be used.

   5 - Security Considerations

   Denial of service attacks (flooding a mailbox with junk) will be easier
   after this document becomes a standard.
