You asked about reaching consensus and I think that that is an important part of the culture of the IETF; it is a very flat organisation, although a few humps
and bumps have appeared over the years.

One of the more recent of these is the Administrative Director; it was he who informed us of the changeover of provider, who kept us abreast of developments, so it is he I see as your customer via whom requests such as those relating to
anti-spam measures should come.

The IAD acts on the behalf of the IAOC.

I agree, however, that consensus on this matter should be obtained on the IETF mailing list.
Consensus of working group chairs is not the same as IETF consensus.

I would expect him to consult, and the customary way to do so is via the IETF main mailing list. However, e-mail is a topic where the list has many experts, whose opinion may be divided, especially where spam is concerned, so I think
that achieving rough consensus there may be difficult.

There is also a dedicated anti-spam mailing list but that has even more experts
and I suspect that consensus will be even harder to reach there.

Nonetheless, I think that the process to follow is clear (and as I write this, I am aware that achieving consensus on IETF process is even more fraught than
achieving consensus on e-mail:-(

Whatever the outcome, I believe that the Administrative Director should announce it on the IETF and announce lists so that participants can adjust their DNS
entries etc accordingly.

Accordingly, here we have a situation where we have a rule that
is:
(1) easy for any spammer to bypass
(2) can be shown to have blocked legitimate mail in at least two cases [Note, you say "defer", but since the issue here is hosts without records, not DNS failures, defer is just a particularly inconvenient
    form of block.]
I think that presents a convincing argument for *at minimum* replacing
the defer with a check in SpamAssassin and, arguably, removing the
check entirely.

I read, and agree with this completely.

That's good, but I don't think it changes the fact that we need a backup

Agreed also. Addressed in my other outage message, which crossed with
this one.

Other comments from anyone regarding rules?

Thanks, Eric!
