We can't send e-mail to one of our clients. It sits in the transfer queue and generates a delay, then failure eventually. The domain I am talking about is remotedomain.com
Other email is flowing fine, and we can receive email from them.
It doesn't look to be making it to their end at all, so I don't believe it to be a spam filter issue.
Exchange queue states "The remote server did not respond to a connection attempt"
Message history shows the last external step to be- "SMTP: Message Routed and Queued for Remote Delivery"
nslookup with type=mx times out.
A tracert to remotedomain.com times out after the hop at-
I tried the tracert from a completely separate DSL connection we have here that doesn't touch my production network, and it timed out at the same point.
And nslookup from the DSL connection yields the same time out result as from my production network.
I am in the Chicagoland area. I had a friend at his work do an nslookup and his worked fine. He is located about 50 miles away from me. I am waiting for tracert results to see what his shows.
Looking for any idea's what this could be. The fact that from two separate ISP connections here it doesn't work seems strange to me.
