Mailman's outgoing message which includes the addresses of all
recipients in the message's metadata is in one out/ queue entry.
Whatever slice that's in, it will be picked up by the OutgoingRunner
processing that slice of the queue and all recipients will be delivered
to that runner's outgoing MTA (default on localhost).

Perhaps there is also some load balancing between MTAs that allows them
to share the delivery.
