yes, it is 72 hours in my server. -----Original Message----- From: Dêniz Feital (Chiptek) [mailto:dfeital@xxxxxxxxxxxxx] Sent: Friday, January 17, 2003 8:01 PM To: [ExchangeList] Subject: [exchangelist] RE: Exchange 5.5 Question http://www.MSExchange.org/ Hi there, Thats Ok. The messages remain on the queue as much time as the IMC is configured for. I mean, The messages have a time-out to be delivered. After that, the message leaves the queue and go back to the sender with a NDR (Non Delivery Report). You can increase the time (the messages will stay at the queue longer) or do the opposite to get the messages off the queue fastly. I am not sure but I think the default value is 72 hours. Regards.

When I check Internet Mail Service Queue, I see that some of messages remain and when I check the details, it says "host unreachable" althoug our DNS works properly. I checked it with nslookup on mail server ant it returns the mx records of these "unreachable" domains. Any idea?
