There is a patch at
which is included in the Mailman 2.1.10 base. This enables putting
list B in one of list A's *_these_nonmembers via the syntax @listb.

With Mailman 2.1.10 or with the patch in prior versions, you can put
@listb in lista's hold_these_nonmembers to accomplish what you want.

Note that you don't want to use accept_these_nonmembers, as that will
bypass moderation.

It's as simple as installing the patch or upgrading to Mailman 2.1.10
(currently in beta with a release candidate due soon). All you need to
do is convince your provider to do it.<wink>
