So your real issue is why is it proceeding so slowly.

Is the MTA doing DNS verification on incoming mail from Mailman? Are
you having some DNS issue?

Slow response from the MTA. Even with SMTP_MAX_RCPTS set to 3, you
should be delivering on the order of 100 or more recipients per
second. What do you see in Mailman's smtp log for processing tomes for
messages. How do the latest ones compare to those from days or a week

It will when it finishes this one.
