Thanks for the tip! This list does have a `pipeline` attribute.

It seems to have both SpamDetect and CookHeaders. Our other mailing
lists do not have a pipeline attribute defined though.
Suspiciously, this pipeline is missing the WrapMessage stage present
in the GLOBAL_PIPELINE. I wonder if that could be the problem?
Yes, the absence of WrapMessage is the problem. I forgot that
WrapMessage also is the piece that actually replaces the original
From:. SpamDetect is where we determine that the message needs DMARC
mitigation, and CookHeaders is where we figure what the munged From:
should look like, but CookHeaders only puts in in the messages
metadata and WrapMessage actually does the replacement.
Thanks for the extra context. I'm beginning to understand how this
works now.
If you were to add WrapMessge, the only difference between this and
GLOBAL_PIPELINE is this one added DeDuper at the beginning. Since I
don't know what that does, I don't know if it's important or not, but
if it is, you could restore the list's pipeline with the addition of
WrapMessage.
The DeDuper is a local addition we have (and it exists in our
GLOBAL_PIPELINE). It keeps a cache of recently seen message-ids on the
list and discards duplicates. This is in place because our lists can be
addressed both as freebsd-curr...@freebsd.org and curr...@freebsd.org.
When someone does reply-all to a message with an original To: header of
curr...@freebsd.org, two copies of the message arrive at the list.
