3.2.13 Injection-Info
The Injection-Info header provides information as to how an article
entered the Netnews system and to assist in tracing its true origin.
It can also specify one or more addresses where complaints concerning
the poster of the article may be sent.
injection-info = "Injection-Info:" SP [CFWS] path-identity [CFWS]
*( ";" inj-info-para ) CRLF
inj-info-param = post-host-param /
post-account-param /

[[Should also allow for x-attributes?]]
post-host-param = "posting-host" "=" host-value
host-value = dot-atom / [ dot-atom ":" ]
( IPv4address / IPv6address ) ; see [RFC 2373]
post-acct-param = "posting-account" "=" value
sender-param = "sender" "=" sender-value
sender-value = mailbox / "verified"
logging-param = "logging-data" "=" value
complainto-param= "complaints-to" "=" address-list
Although comments and folding of white space are permitted throughout
the Injection-Info header, it is RECOMMENDED that folding is not used
within any parameter (but only before or after the ";" separating
those parameters), and that comments are only used following the last
parameter.
This header is intended to replace various currently-used but
undocumented headers such as "NNTP-Posting-Host", "X-Trace" and
"X-Complaints-To". These headers are thus deprecated.
The "posting-host" parameter specifies the FQDN and/or IP address
(IPv4address or IPv6address) of the host from which the injecting
agent received the article.
NOTE: If the "posting-host" parameter identifies a dial-up point-
of-presence, the "posting-account" or the "logging-data" parameter
may provide additional information about true origin of the
article.
The "posting-account" parameter identifies the source from which the
injecting agent received the article. For security reasons, it
SHOULD be in a cryptic notation understandable only by the
administrator of the injecting agent.
The "sender" parameter identifies the mailbox of the verified sender
of the article (alternatively, it uses the token "verified" to
indicate that at least any addr-spec in the Sender header of the
article, or in the From header if the Sender header is absent, is
correct). If an injecting agent can verify sender of an article, it
SHOULD use this parameter in favour of the "posting-account"
parameter.
The "logging-data" parameter contains information (typically a
session number or other non-persistent means of identifying a posting
account) which will enable the true origin of the article to be
determined by reference to logging information kept by the injecting
agent.
The "complaints-to" parameter specifies mailbox(es) for sending
complaints concerning the behaviour of the poster of the article.
