MessageHi, i'm using w2k with Exchange 2000. When i get NDR, i always get this, example : This is an automatically generated Delivery Status Notification. Delivery to the following recipients failed. test@xxxxxxx (this when i send to unknown username) i want to know how to make NDR more spesific reports ? eq, it says no username like that or maybe like this : Hi. This is the qmail-send program at pop3.central.net.id. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <test@xxxxxxx>: 143.61.200.6 does not like recipient. Remote host said: 550 5.7.1 <test@xxxxxxx>... Relaying denied. IP name lookup failed [203.77.255.2] Giving up on 143.61.200.6. thx Hery
