The IESG has received a request from the Usenet Article Standard Update
WG (usefor) to consider the following document:
- 'Netnews Architecture and Protocols '
<draft-ietf-usefor-usepro-12.txt> as a Proposed Standard
Section 3.4 of this I-D states that:
"Contrary to [RFC2822], which implies that the mailbox or mailboxes in
the From header field should be that of the poster or posters, a
poster who does not, for whatever reason, wish to use his own mailbox
MAY use any mailbox ending in the top level domain ".invalid"
[RFC2606]."
The use of an invalid email address for the author can be a problem
if the message goes through a news-to-mail gateway. Section 3.10.1
(Duties of an Outgoing Gateway) doesn't mention what should be done
in such a case. Section 3.6.2 of RFC 2822 mentions that:
"In all cases, the "From:" field SHOULD NOT contain any mailbox that
does not belong to the author(s) of the message."
Should such messages be discarded by a news-to-mail gateway as they
are not meaningful in that medium?
That could be avoided by encapsulating the message in a new message
and sending it with Content-Type application/news-transmission. Such
messages might show up as attachments in some MUAs though.
In Section 3.5.1:
"The proto-article is sent as an email with the addition of any
header fields (such as a To header field) required for an email."
The To header field is not required; the From header is. I suggest:
The proto-article is sent as an email with the addition of any
header fields required for an email as defined in RFC2822.
Section 3.10.2 recommends the following for an incoming gateway:
"If the original message already had a Sender header field, it SHOULD be
renamed so that its contents can be preserved."
The draft doesn't specify to what the header should be renamed. I
suggest creating a new header field for it.
If the original message already had a Sender header field, it SHOULD be
renamed to original-sender so that its contents can be preserved.
original-sender = "Original-Sender:" mailbox CRLF
A request to IANA to update the the Permanent Message Header Field
Repository with the following is required:
Header field name: Original-Sender
Applicable protocol: Netnews
Status: standard
Author/Change controller: IETF
Specification document(s): This document (section 3.10.2)
In Section 3.10.3, it is mentioned that:
"The news-to-mail gateway adds an X-Gateway header field to all
messages it generates."
It may be better to depreciate the use of X- headers.
