Hello list! My exchange 2000 server sp3, can't send mail to some domains, such as aol.com, yahoo.com When I open the queues properties for this domain, I see non-delivery reason "Unable to bind to the destination server in DNS" Most of other domain are working propely.. When I'm trying to find MX serever for theese domains, I get the following: C:\nslookup Default Server: ################## Address: 10.1.###### > set type=mx > aol.com Server: ################### Address: 10.1.##### aol.com primary name server = dns-01.ns.aol.com responsible mail addr = hostmaster.aol.net serial = 2005011301 refresh = 1800 (30 mins) retry = 300 (5 mins) expire = 604800 (7 days) default TTL = 600 (10 mins) > If someone had faced such a problem, please advise something Sincerely Denis N Fedorus
