Mark,
This is the DNS record entry that seems to have fixed the problem:
NAME: @
TYPE: TXT
VALUE: v=spf1 mx include:netblocks.dreamhost.com
include:relay.mailchannels.net -all
Dream Host runs GNU Mailman version 2.1.39 (but I SWEAR it was 2.1.23
earlier this morning!).
I already had General Options set to "Munge From" all along (including
when I as getting Gmail yellow box).
Under Privacy options... -> Sender filters, I have:
dmarc_moderation_action = Accept
dmarc_quarantine_moderation_action = Yes
Possibly stupid question -- Does it make any sense to also change
dmarc_moderation_action to Munge From under Privacy options --> Sender
Filters?
Thanks,
Michael

Dreamhost should be DKIM signing the outgoing list mail with the
list's domain. If they aren't you can ask them to do it, and they can
come here for help if they need it.
It may not be an issue, but you should also enable DMARC mitigations.
For Mailman >= 2.1.18, in Privacy options... -> Sender filters, set
dmarc_moderation_action to Munge From and
dmarc_quarantine_moderation_action) to Yes. Older versions 2.1.16 and
2.1.17 you can set General Options from_is list to Munge From, but
this requires setting ALLOW_FROM_IS_LIST to Yes in mm_cfg.py. This is
also available in 2.1.18+, and will apply mitigations to all messages,
not just ones publishing DMARC polocy reject or quarantine,
This is freaking out a few of my users. I'm attaching a screenshot of
the message and source code for the same message.?? Hopefully this
list allows attachments...
Not images, only attached messages, text and pgp ang pkcs7 signatures.
