Does Mailman deliver directly to the remote server or via Postfix? If
directly, what does Mailman's smtp log say about the posts that were
delayed. I.e. a post to a list will have an entry like

May 09 12:53:47 2013 (6114)
<009b01ce4cee$e4c00540$ae400fc0$@xxx at example.com> smtp to LISTNAME for
237 recips, completed in 4.337 seconds

which says the the message with message-id
<009b01ce4cee$e4c00540$ae400fc0$@xxx at example.com> was delivered from the
LISTNAME list to (in this case) 237 reqular subscribers and SMTP to the
MTSA was completed at 12:53:47 (and started 4.337 seconds earlier).

I suspect they were delivered to the remote server well before and not
all at once at noon.

If Mailman delivers via Postfix, what does the maillog say about those
