Hi Leigh, I am investigating the issue. My first question is: did you get your "
test" message in your inbox? If you received that message, then mailman probably sent the message to all subscribers. Then the problem would be on the Nabble side. But if you didn't get anything in your inbox, then mailman is probably rejecting messages from Nabble users. Do you have a log on the mailman server that could give us more information?
