Well, I ran into this just the other day. One list I'm on moved from
one server running Mailman to another running ezmlm. I had been
subscribed to the list with two addresses: one which fed into my local
(private) news server to archive the messages and make for easier
reading, and the other as "nomail" to post to the list.
With the move to ezmlm, it insists on subscribing the envelope sender
address, which makes it quite difficult to subscribe my news server's
address. Aside from that ezmlm has no "nomail" setting, so I just left
that list... :-(
I therefore believe that the right thing to do is to use the header
"From:" address, as it provides for more flexibility (and no, SPF won't
protect you from forging that, since it applies to envelope sender).
