I assume there's nothing in /var/lib/mailman/logs/smtp-failure since if
there were, these would also be recorded as bounces.

Mailman did complete SMTP to Postfix for all 416 recipients. The
/var/lib/mailman/logs/smtp log entry verifies that. What happened after
that is a Postfix question.

I don't think this should happen without Postfix logging something, but
if I have to guess, I'd guess you are not VERPing delivery to Postfix
and the list is not personalized so Mailman is delivering to Postfix in
transactions with up to SMTP_MAX_RCPTS (default 500) per transaction and
Postfix's smtpd_recipient_limit is less.
I suggest you set SMTP_MAX_RCPTS = 10 or 20 in mm_cfg.py or better set
VERP_DELIVERY_INTERVAL = 1 to enable VERP on all deliveries.
