yes, i can/could. I think I even decreased it to 1h now. But if I set this to a very short time and there is a hiccup in the network, the internal server sends lots of "mail delivery delayed". Thus I like to keep the threshold to something >1h so that notifications are only triggered if there is a serious network problem. > > I guess the internal server is not Postfix, because by default Postfix does > not send notifications about temporary failures (delay_warning_time is set > to 0 by default). That is an interesting way to come to this conclusion :) but the conclusion is in fact true: the internal server currently is not Postfix. Cheers, Simon
