Please do not waste your time with verbose logging. Please do not waste your time with debuggers, LONG BEFORE the queue manager defers mail with "unknown transport error", some other part of Postfix will log a WARNING:, FATAL: or PANIC: record with the reason why the program is failing. This is why I point you to DEBUG_README.html#logging and not to the other DEBUG_README sections. Wietse
