Some things to check:

1) that the machine that *is* handling mail hub service for bna.com
is aware of special forwarding needed for Listserv.  You will also need
forwarding for all the administrivia addresses for *each* list that you
set up.

2) You will need to do some magic in listserv's sendmail so that it realizes
that mail for 'listserv@domain' should *NOT* be forwarded out (but that mail
for [log in to unmask] *should* be sent to the mail hub.  Hint: Use
the 'map' facility in Sendmail 8.8.5 to do this.

3) The '@@host' problem sounds suspiciously like you didn't configure
masquerading quite correctly.  You should check over the .mc files for
both your listserv and mailhub machines...
