FWIW, sendmail is an exceedingly poor MTA when it comes to
Mailman. The only way to get it to have reasonable throughput
seems to be to put it in DeliveryMode=defer, which makes it
hard to get posts out the door quickly. They will get held up
until the next queue run, and that can take a long time if
there are DNS resolution problems or connection delays.
Putting sendmail into defer mode seems to be the only way to
stop it doing DNS resolution on every "RCPT TO:<luser at domaon>"
that it gets.
