Use of ADSP

Hello all,

There's been a proposal put forth in the standards community to move ADSP
(RFC5617) to Historic status from Proposed Standard. The main reasons are
(a) its lack of substantial uptake, and (b) the fact that it can be
actively damaging, such as in the case of use when mailing lists are
involved.

Since those are the premises of the move, I wonder if anyone has anecdotes
to share that illustrate useful benefit from using it. So here are the
relevant questions to OpenDKIM:

1a) If you use OpenDKIM as a filter, do you have it enabled (the default)
and set to reject (not the default)?

1b) If you use OpenDKIM as a filter with ADSP enabled and do not reject, it
adds an Authentication-Results header field indicating the failure. Do you
do anything with that?

2a) Do you use libopendkim directly? Specifically, do you call
dkim_policy() and related functions to do ADSP checking?

2b) Do you act on the result, or merely attach it to the message so
something downstream can handle it?

Thanks,

-MSK
