With the old "crystal ball" out for repair, it is rather hard to say. You might consider reading the documentation located at: http://www.postfix.org/DEBUG_README.html#mail and following the directions. Including log specific data is also a helpful endeavor. By the way, have you considered asking this question on the Mailman forum? -- Jerry
