Whenever I post something to the list (I'm not using SMTP, I'm
using a usenet server to post to comp.protocols.dns.bind), my
postmaster address receives DMARC notifications from list members
that have employed this wonderful protocol on their servers,
telling me my message had been rejected for violating my SPF
policy.
My SPF record doesn't include lists.ist.org
<http://lists.ist.org/>, of course and it never will. Furthermore
it ends with "-all" so all my messages to the list are being
rejected by list members who have spf aware servers.
SPF must only check envelope address, not header From: address
- it was never designed to do the latter.

Just found another solution, that will help with any DMARC-aware
server that knows Sender-ID. I just published:
heikorichter.name. 60 IN TXT "spf2.0/pra ?all"
This will force DMARC to check only the envelope sender, which is
changed by lists.isc.org as /dev/rob0 pointed out earlier....
How did your SenderID record look before?
Note that it's the SenderID specification that is horribly broken (btw, just
because of mailing lists) and further any protocol that uses it (does
DMARC?)
Blaming the ISC mailserver for not changing header address is blaming it for
doing something (all?) list servers did years before microsoft came with the
braindead SenderID specification that broke this behaviour.
