Steve: Fair enough. The issue ultimately was with Postfix, but I only encountered it because I misread the Mailman3 configuration wiki as setting "virtual_alias_maps = hash:/path-to-mailman/var/data/postfix_vmap" to be /path-to-mailman/var/data/postfix_lmtp. The lmtp versus vmap distinction made a large difference. I'm not sure where I picked that error up or whether I just imagined it myself.
Fixed now!
Thank you.

I don't understand why this is a Mailman problem. Seems like Postfix user lists would be a better venue to get expert help with this. Among other things, our most responsive Postfix guy is out of cell coverage for now.
I would post this To: the relevant Postfix list, Cc: this list, and set Reply-To and Mail-Followups-To to the Postfix list to get everybody who can contribute on the same page.
If it is a Mailman problem, you have my apologies and I'm listening.
