Hello,
I have a newly installed Exchange 2013 working just dandy, except that it cannot relay mail for two particular domains.
Problem domain # 1 gives me an NDR:
primary target IP address: "Failed to connect. Winsock error code: 10061,
Win32 error code: 10061." Attempted failover to alternate host, but that
did not succeed. Either there are no alternate hosts, or delivery failed to all
alternate hosts. The last endpoint attempted was 72.52.10.14:25'
Problem domain # 2 gives me a useless NDR:
Remote Server returned '550 4.4.7 QUEUE.Expired; message expired'<u5:p></u5:p>
Tracking messages to both domains I get a common error:
Eastern Time (US & Canada) and generated the error '[{LRT=};{LED=};{FQDN=};{IP=}]'.
Here's what I have done so far:
I can telnet to both problem domains on port 25 and get a 220
DNS resolves both mail server FQDN's to the correct IP
Using NSLOOKUP I can see MX records for both domains
I have verified EDNS using OARC's site
Currently I am stumped. Any suggestions or help would be greatly appreciated.
