Brad is correct, but note that if you look at Mailman's smtp log, you
should find the "<message-id> smtp for nnnn recips, completed in
xxx.xxx seconds" log entry relating to your Oct 25 message. At the
time that entry was written, Mailman was done delivering that message
except for possible retries of temporary failures occurring in
delivery to the outgoing MTA. These failures if any will be logged in
Mailman's smtp-failure log. Mailman will continue to retry the
temporary failures for DELIVERY_RETRY_PERIOD (default 5 days)
following the original failure.

Once Mailman has handed the delivery to the MTA and logged it in
'smtp', subsequent delays are in the MTA or further outbound, so you
might get more information from your MTA's logs.
