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. > Maybe close off the RFC with a sample /etc/aliases file that has all the > suggested names aliased to an account named "admin" including some > comments for the ones (USENET) that are likely to be needed on other than > a mail server. Remember, this RFC will be read by a lot more newbies than > most RFC's. 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.) > From: James Aldridge <[email protected]> > > [...] > > This list should probably also contain `hostmaster' as the contact for > DNS-related matters.

Stan beat you to this suggestion, but thanks just the same. Operational Requirements Area Paul Vixie (ISC) INTERNET-DRAFT May, 1996 <draft-vixie-ops-stdaddr-01.txt> 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.'' To learn the current status of any Internet-Draft, please check the ``1id-abstracts.txt'' listing contained in the Internet-Drafts Shadow Directories on ftp.is.co.za (Africa), nic.nordu.net (Europe), munnari.oz.au (Pacific Rim), ds.internic.net (US East Coast), or ftp.isi.edu (US West Coast). 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.'' Expires November 1996 [Page 1] 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]>. Expires November 1996 [Page 2] 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 Expires November 1996 [Page 3] INTERNET-DRAFT STD ADDR May 1996 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. 6 - References [RFC821] J.
