That's what I do on my lists.  It was pretty easy to add in the shim
that adds the outgoing DKIM signature, and is the least painful thing
I could think of for my mostly non-technical users.

>(or maybe instead of yahoo.com.INVALID, it should be "yahoo.com.BREAKS.MAILING.LISTS"

Now, now, there's no LISTS TLD.  Yet.

R's,
