I have recently (last couple weeks?) started getting "4.3.0 mail transport unavailable” bounces from roadrunner/TW addresses (the rate-limiting issue is not currently rearing its head), and that is causing Mailman (2.1.17) subscriptions to be disabled. Example error message in the “Bounce action notification” email:
Reporting-MTA: dns; zapata.dreamhost.com X-Postfix-Queue-ID: B6D6B8DB0B72 X-Postfix-Sender: rfc822; neohiopal-bounces@lists.neohiopal.org Arrival-Date: Mon, 9 Jun 2014 05:15:45 -0700 (PDT)

From googling it appears this is may be a Postfix problem? Any one else seeing this with roadrunner/time warner?
Yes, it would seem to be a problem with Postfix at zapata.dreamhost.com. Is dreamhost.com your Mailman host or a downstream relay in this case? If they are your outbound MTA, it seems strange that this would affect only mail to the roadrunner.com domain, but in any case, I think it's up to Dreamhost to fix it.
