It's really simple. If an interoperability problem arises from your failure to implement a SHOULD, then it's your fault. --apb (Alan Barrett) ___ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf

On Mon, 28 Dec 2009, John Levine wrote: But I see little wisdom in adding another does-not-exist name with semantics not meaningfully different from .INVALID or FOO.INVALID.

Re: Last Call: draft-jabley-sink-arpa (The Eternal Non-Existence of SINK.ARPA (and other stories)) to BCP

In the examples, I would like to see reinforcement of the above principle. For example, the should in Installing an MX record ... should cause compliant MTAs to ... is a prediction about the behaviour of compliant MTAs when encountering *any* nonexistent domain name; it is not a requirement for special treatment of the SINK.ARPA name, but some people might interpret the exmple as a requirement for special treatment. I don't like the name SINK much; calling something a sink implies that traffic can be sent to it, and that such traffic will be read and discarded, but that's not what's going on here. I prefer NONEXISTENT.ARPA or some variation on that theme. --apb (Alan Barrett) ___ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf

I have no problem at all with user-controlled filters that do whatever they want. It's when an ISP starts doing these things on behalf of a user who doesn't understand or want them that the problems arise. Your remedy should be truth-in-advertising enforcement, as Vernon said. Entities that filter in the way that you don't like are not providing real Internet access, and should not pretend to. --apb (Alan Barrett)

Eliminating the ability to have new people show up without an appointment will cripple some activities. It ought to be possible to consent to contact without an appointment. For example, you could have a protocol that allows you to encode rules like I consent to receiving messages from new people, provided that the messages purport to be related to certain specified topics, and provided that one of a set of specified escrow agents vouches for the existence of a bond of a specified value to be paid if the message is not what it purports to be. --apb (Alan Barrett)

After the BIND company (1) issues an RFC that clearly allows NXDOMAIN in this situation, (2) tells a new implementor that NXDOMAIN in this situation is fine, (3) publishes BIND 9, which uses NXDOMAIN in this situation, and (4) allows this use of NXDOMAIN to be deployed for four years, (1) did not happen. (2) was a mistake by one person, not by a company or the IETF. (3) is a bug in bind 9. (4) is a bug in bind 9. you think it's perfectly reasonable for the BIND company to change its mind and publish a new RFC saying---without a shred of justification--- that NXDOMAIN in this situation is prohibited?

Last Call: MIME Security with OpenPGP to Proposed Standard
On Fri, 27 Apr 2001, The IESG wrote: The IESG has received a request from the An Open Specification for Pretty Good Privacy Working Group to consider MIME Security with OpenPGP draft-ietf-openpgp-mime-06.txt as a Proposed Standard. draft-ietf-openpgp-mime-06.txt assumes that the content-transfer-encoding of a body part in a multipart MIME message will remain unchanged end to end. That assumption is not valid. Some currently deployed mailers (including sendmail) will convert body parts to or from 8bit content-transfer-encoding. It's quite possible that a body part could originate in quoted-printable, be signed like that, and be converted to 8bit before delivery. In 1998, many messages to the IETF list ended up with headers like this, showing conversion to 8bit during delivery of the incoming message to the list exploder, and conversion from 8bit during delivery of the outgoing messages to the subscribers: X-MIME-Autoconverted: from Quoted-printable to 8bit by ietf.org id LAA20175 X-MIME-Autoconverted: from 8bit to quoted-printable by ietf.org id LAB20435 Similar behaviour is visible today in other mailing lists, but apparently not the ietf list. I believe that it's a mistake for OpenPGP to sign the transfer-encoded form of any message. The signature should be over the canonical form of the message, and signature verification should be insensitive to changes in content-transfer-encoding. --apb (Alan Barrett)
