My guess is that new members are added to the list on the new server,
but the MX for the list domain still points to the old server so that
posts to the list go to the old server where the new members aren't on
the list.

It could also be that DNS has been updated but the old MX and/or A
records had long time to live and haven't aged out of some users' DNS
caches yet, but this seems unlikely.

You could check Mailman's 'post' log on both servers to see which one is
processing posts.
