Note that much of the delay was likely due to mailman hitting tarpit
controls after 10 invalid recipients in a single submission.

Although slow DNS lookups could well have contributed.
For submission of list messages to a large number of recipients,
I would generally use sendmail(1) rather than SMTP. Don't know
whether mailman supports that.
