[Mailman-Users] Munge-from "From:" addresses and address auto-complete

We have a number of Mailman V2 lists with "Munge-from" turned on, due to
DMARC issues at receiving mail systems. This rewrites the From:
addresses to something like:
From: Dan Halbert via SOME-LIST <SOME-LIST at example.org>
The problem is some email clients (I'm not sure which ones) pick up
these "From:" addresses and add them automatically to the user's address
book. Then, when the user wants to send a private (not list) message to
some person on the mailing list, they start typing the person's name,
and the email client may autocomplete with the list address, not the
person's address. If the sender doesn't check the address carefully,
they may send to the list inadvertently. This has led to several mildly
embarrassing private messages being sent to a list.
Is there some configuration I can set up that can alter these "From:"
addresses to avoid putting the person's name first, but still including
it? Or is there some other way to ameliorate this problem? We could
choose something other than "Munge-from", but we do not want to lose the
identity of the sender, which is worse.
We are using a third-party provider and have no direct control over the
formatting of the rewritten "From:" header; I would change the Mailman
code directly if I could.
Thanks,
Dan
