Mailman is trying to send some notices to 'kelly' and 'lynn' and Postfix is not accepting them with a 450 status. Since it is a 4xx retryable status, Mailman keeps retrying every 15 minutes. Mailman will eventually give up and return bounces after 5 days (default DELIVERY_RETRY_PERIOD).
In order to help you proceed, I'd like to see the output from 'postconf -n' and the postfix log message from one of the above rejects.
Note that the above messages are not really Mailman related. They don't indicate that Postfix can't deliver to Mailman, although that may also be true. They indicate that Postfix cannot deliver to 'lynn' or 'kelly'. If these should be valid, deliverable addresses, there is a Postfix configuration issue. If they are in fact invalid, you can check your main.cf settings for things like 'soft_bounce' and 'unknown_virtual_mailbox_reject_code'. You may want 'soft_bounce = no' and unknown_virtual_mailbox_reject_code = 550.
Also, to get rid of these retries before they expire, you can remove the four $prefix/qfiles/retry/*.pck files. You can also do
$prefix/bin/show_qfiles $prefix/qfiles/retry/*.pck
to see what the messages are.
