The above setting has nothing to do with this. The message in your
smtp-failure log comes from your MTA because Mailman is sending
messages with a number of recipients (SMTP RCPT TO) greater than your
MTA will accept.

In mm_cfg.py, set SMTP_MAX_RCPTS to a number less than the MTA's
recipient limit, and restart Mailman.
