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.
