I do that now using procmail and the schuller+listname@lunatech.com
syntax supported by sendmail. The listname is available in procmail as
$1, so that's easy.

No, that would be if they too looked at the envelope. No list that I
know of requires that. Setting "From:" can be done by your MUA, as it's
just a header. Mutt certainly has no problem with it.
