It looks like the delay is between delivery to Mailman and delivery
from Mailman. You could confirm this by grepping the Postfix log
(/var/log/maillog ?) for the queue IDs 5D6E724B62 and 4329A23BBE.
Also, the log messages for queue ID 4329A23BBE will show whether the
delay is in Postfix or not.

Do you have access to this log? Do you have access to Mailman's logs
and files. If so, what's in Mailman's 'smtp' and 'smtp-failure' logs
with time stamps in the one hour or so range beginning Fri, 16 Sep
2011 18:47:42?
