So after a upgrade from 8.0.0 to 8.0.2 our users have started to get successful mail delivery reports. The problem is they dont want it. Is there a way to turn it off, the other issue is we also upgrade the spam filter around the same time so i dont know if it was the groupwise upgrade that created this or the spam filter. I did notice the ESMTP setting in the gwia and it looks new so disable it and restarted the gwia but they are still getting the messages.
