Did you set max_recipients in the mta section of mailman.cfg. That controls the maximum number of recipients of a message. The default is 10. Is that the number of recipients you're seeing in the rejected messages.
Right now it appears to be obeying the destination_recipient_limit (5) in my postfix configuration, but it's not obeying the destination_concurrency_limit (1), and hitting their servers with a bunch of connections at the same time. My research into postfix configuration continues.
I wonder if I should set max_recipients to 0 in Mailman, and let Postfix decide how many recipients, if things would be a bit happier?
