I am running Mailman via CPANEL and I am not having these issues - are you using CPANEL ?
When I lookup livingaudio.net <http://livingaudio.net/> it shows that there is no DMARC record for that domain ? Most of the email servers in the world now require DMARC records or they will reject your emails.
