Is it possible that the e-mail addresses or IP addresses affected within topics All posts via Nabble forum 1653123 failing [since around 2009-09-10] or Mailman subscribers unable to post have fallen into a black hole, or on to a grey list?

Of possible relevance: maybe twice in recent weeks I am advised that the domain of the address that I have registered with Nabble was associated with returns (as undeliverable) from Hotmail, MSN and Windows Live recipients. I noticed no such returns, probably because I attempted to address no-one in those domains during the affected period(s). Now I wonder whether addresses remain grey- or black-listed in places.
