With  version 1.8a  you  can request  LISTSERV  to generate  domain-style
addresses when it refers to the list address. With 1.7f you would have to
code specific "Sender=" and "Reply-To="  keywords. At any rate, your SMTP
should be  configured to  rewrite headers  so that  it can  avoid sending
.BITNET addresses into the Internet.
