One little question: Is it a goal to make Gnus pass the GNKSA test? It
seems to fail on a rather minor issue...

I've made the From checks more thorough in Gnus 5.4, so it should pass
now.

It seems the current Gnus could pass the GNKSA. Maybe Gareth Rees could

Technically, yes, they should just be ignored. But I can't see any
reason they should be allowed in email-addresses, however tyrannical and
paranoid that approach may seem ;)

Hmmm...for some reason, I thought it only applied to the named database
configuration files and not general hostname lookups?

Theoretically, but in general its a good thing to check for. 80+% of the
time it will be indicative of a bad setup.

I believe it's a hack to let people tell the resolver not to try
tacking on domains in it's search list (which is also considered a
hack, I believe).
Disclaimer: All those "I believe"s translate to "somewhat certain but
too lazy to check".

Uh. The question is not should they be allowed, it's "is there any
reason not to allow them"? If I mail to "foo@zub.fi", and there's an
fi subdomain here at CMU, but I really mean zub.fi (in finland), I
should be able to type "foo@zub.fi." to get it.
Do you see any reason why this shouldn't be allowed?
John.

Technically, if you do not have a trailing period, the name is not fully
qualified. In practice it is not usually required as your resolver is
supposed to add it somewhere in its resolution loop.

One could argue that if your site has subdomains with the same name as
your top-domain, you're getting what you deserve. One could also argue
that you're right. There IS no reason to not allowing names like
foo.com., ASSUMING your nameserver/sendmail-equivlant knows how to
handle it. But I guess this is along the same lines as expecting
internet sites to have a postmaster-mailbox...

No, you should be able to type "foo@zub.fi". To get at the "local" fi
subdomain you should be typing the full host name, which is required for
*ALL* Internet mail, even if zub.fi.cs.cmu.edu is literally right next
to the one you are sending from. Local names should only be used
locally, that is, on the same machine (and really then only if the
machine is not on any network).

I went and checked 822 in the hopes of killing this thread before it
wells up. :/ Essentially, 822 doesn't allow it.
People use it with tools like dig/host/etc. coz they're used to having
that form short cut the resolver. W/o the resolver hack, the trailing
period indicates the root domain and is therefore superfluous. It's
illegal in mail.
The evidence follows,
-Sudish
[ Severely edited, from RFC 822 ]
address = mailbox
mailbox = addr-spec
addr-spec = local-part "@" domain
domain = sub-domain *("." sub-domain)
sub-domain = domain-ref / domain-literal
domain-ref = atom
atom = 1*<any CHAR except specials, SPACE and CTLs>
specials = "(" / ")" / "<" / ">" / "@" ; Must be in quoted-
/ "," / ";" / ":" / "\" / <"> ; string, to use
/ "." / "[" / "]" ; within a word.
[ I.e., no "."'s in sub-domains, and all except the first subdomain
are preceded by "."'s ]
[ From paragraphs 3 and 4 in section 6.2.1 of 822, "Domains" ]
The root node is common to all addresses; consequently, it is
not referenced. [...]
The "top" of the domain addressing hierarchy -- a child of the
root -- is indicated by the right-most field, in a domain
specification. [...]

No. 822 explicitly allows compression of domain names--which is quite
funny, coz it has no relevance to what happens between co-operating
hosts. Like that other pastime, they can do whatever it is that
tickles the parts they like tickled.
Here's the ref in the interests of stillborn speculation,
-Sudish
[ RFC 822, I snipped a page divider ]
6.2.2. ABBREVIATED DOMAIN SPECIFICATION
Since any number of levels is possible within the domain
hierarchy, specification of a fully qualified address can
become inconvenient. This standard permits abbreviated domain
specification, in a special case:
For the address of the sender, call the left-most
sub-domain Level N. In a header address, if all of
the sub-domains above (i.e., to the right of) Level N
are the same as those of the sender, then they do not
have to appear in the specification. Otherwise, the
address must be fully qualified.
This feature is subject to approval by local sub-
domains. Individual sub-domains may require their
member systems, which originate mail, to provide full
domain specification only. When permitted, abbrevia-
tions may be present only while the message stays
within the sub-domain of the sender.
Use of this mechanism requires the sender's sub-domain
to reserve the names of all top-level domains, so that
full specifications can be distinguished from abbrevi-
ated specifications.
For example, if a sender's address is:
sender@registry-A.registry-1.organization-X
and one recipient's address is:
recipient@registry-B.registry-1.organization-X
and another's is:
recipient@registry-C.registry-2.organization-X
then ".registry-1.organization-X" need not be specified in the
the message, but "registry-C.registry-2" DOES have to be
specified. That is, the first two addresses may be abbrevi-
ated, but the third address must be fully specified.
When a message crosses a domain boundary, all addresses must
be specified in the full format, ending with the top-level
name-domain in the right-most field. It is the responsibility
of mail forwarding services to ensure that addresses conform
with this requirement. In the case of abbreviated addresses,
the relaying service must make the necessary expansions. It
should be noted that it often is difficult for such a service
to locate all occurrences of address abbreviations. For exam-
ple, it will not be possible to find such abbreviations within
the body of the message. The "Return-Path" field can aid
recipients in recovering from these errors.

And in this case, where the sub-domain is identical to an outside,
higher-level domain, the message cannot be guaranteed to be "local"
within the sub-domain of the sender. Therefore, the use of this feature
should not be approved for the sub-domain "foo.fi"; approving it would
make it such that mail to "baz@foo.fi" in Finland will never get out of
"foo.fi.com" in the US.
