You're going to have to identify one of the delayed emails and look at
it's headers to see where it was held up. You might also look
at /var/log/maillog and the /var/log/mailman/smtp logs to see if and
when the suspect messages were processed. Missing mail may have also
bounced. Once your MTA hands off a set of mail to a destination SMTP
server a whole host of things can happen to it that has nothing to do
with your server. Your best bet is to verify from the logs the mail left
your server when you expected it to.
