If the domain in a From: address on a list mail has a dmarc entry with

very likely to get blocked.
In that case the list software needs to rewrite From and strip the
existing DKIM signature (and preferably add its own that matches the new
From address). Some lists only rewrite From for senders with p=reject,
but it's quite common now to rewrite From for all senders (in conjunction
with adding your own DKIM this is especially useful if you deliver into
google over IPv6, they have fairly stringent requirements in that case).
That's a fair point.
I've remove the prefix from this mailing list so nothing about the email
should be modified from now onwards.
Hopefully this is the last change needed!
People can still filter by the long standing email headers which are
appended which should not affect DKIM, such as:
List-Id: <dhcpcd-discuss.marples.name>
