This seems quite strange. It is almost certainly not a Mailman issue
per se unless the bounces complained specifically about the envelope
sender of the message (LISTNAME-bounces at LIST.DOMAIN).
Check your Postfix log for the delivery of some of the bounced mail. In
particular, look at the receiving MTA for the mail that bounced vs.
mail to the same address that didn't bounce. Possibly some DNS glitch
caused the first batch to be routed via an incorrect MX.
