That's correct.

That message is delivery of the original incoming post to Mailman.  That
message should be logged at the time Mailman received the message.
I.e., in Mailman's smtp log you see a time stamp and the smtp to list
for 416 recipients in n.nnn seconds. The arrival time is a bit before
the time stamp - n.nnn seconds.
