I don't use postfix, but I'd be surprised if this were a problem with
Mailman.  The message itself claims your MTA can't find a route to the
mx4.mail.yahoo.com, which is acting as a mail exchanger for yahoo.com,
which suggests a routing problem. 

Are you able to send a message a message from the host with Mailman
installed on it to Yahoo?
