Environment: single Exchange 2000 sp3 server not using smarthost for external mail delivery(straight delivery) Using relay server for incoming mail OK! I have an interesting problem, that I'm not sure what to do with. I'm trying to send emails to a particular domain, but I keep getting delivery delayed mails sometime later. I run an smtpdiag from my workstation and everything runs through fine. I run it from the Exchange server and I get this: "Connecting to the server failed. Error: 10060 Failed to submit mail to mail.<domain>.com." Telneting, from the exchange server, to port 25 of that address gave me the same result. Question 1: Why would telneting and running smtpdiag work fine from my workstation, but not from my exchange server? Question 2: How do I fix this? Thanks, Blair
