I assume that there will be a warning message sent back to the "sender" after the mail has been queued for a few hours (we have in Postfix "delay_warning_time = 8"). I assume that the warning message will be sent to the list -bounces address, and that Mailman will process this warning correctly. ---------------------------------------------------------------------- Barry S.
