Signup confirmation and welcome emails are working. They appear to be coming from the intended host, which is 757pug.org
Welcome messages are sent from Mailman core the same way as posts.
But emails from the mailing lists are being blocked by the smtp relay. I think it's because they are not coming from 757pug.org; They are coming from smart.bnmng.com
Assuming the Mailman core list name is xxx@757pug.org, Mailman will send both posts and welcome messages with envelope from xxx-bounces@757pug.org if not VERPed or if VERPed, xxx-bounces+user=example.com@757pug.org. The only difference is the From: header. for a welcome message the From: address is xxx-request@757pug.org. For a post if the list is anonymous or if DMARC mitigations are applied the From: address is xxx@757pug.org. Otherwise it is the From: address of the incoming post.
For failures from the smtp relay, there should be messages in Mailman's smtp.log of the form:
$msgid delivery to $recip failed with code $smtpcode, $smtpmsg
with the appropriate substitutions. What are the error messages in these entries.
