As a newbie to sendmail/majordomo, I wonder: is this a bug in sendmail? Or
there a good reason why sendmail would start another delivery queue? I
recently setup Majordomo specifically to handle a list of about 4,000
entries which was taking many hours to deliver directly from Outlook
Express client. We were about to test it with the 'live' subscriber list
when I caught this thread.
