I'm trying to set the destination_concurrency_limit, but only for one outgoing 
domain (rochester.rr.com) which complains of too many incoming connections when 
my neighborhood announcement mailing list, which has about 50 people with 
rochester.rr.com email address subscribed. 39 of those members just got 
unsubscribed, and since this list is run for little old ladies who barely 
understand that their computer has to be on in order to receive email, we tend 
to manage the subscriptions and re-subscriptions manually rather than ask the 
end users to do it.

In mailman 2, I had my mailing list aliases in the virtual_alias_maps, and now 
in mailman 3 it's in transport-maps, and it's meant that some of the 
configuration I had before doesn't work.
