[luv-main] Luv mailing list domains

I just realized (too late, unfortunately) that Mutt's reply to list feature is now generating a "To" field like this: luv-main@lists.luv.asn.au, luv-main@luv.asn.au I think the cause may be this header in messages distributed via the list: List-Post: <mailto:luv-main@lists.luv.asn.au> whereas the "To" header gives luv-main@luv.asn.au as the address. Would it be possible for our hard-working and diligent administrators to get rid of the lists.luv.asn.au domain in the headers? I don't know enough about mailman configuration to appreciate how much work this would require. I might be able to work around this in my Mutt configuration, but I think it's best fixed at the source, if possible.
