SMTP DNS Resolution problem

We have just setup our notes server and are having a problem with Outbound SMTP being able to resolve destination host names. I can run nslookup on the server and am able to resolve the destinations. As an interm I have put the ISPs relay in place but even had to add a entry to the hosts table for it. We are switching ISPs down the road and will not have a relay available. When I just have the hostname of the relay in place I get

SMTPClient: Attempting to Connect: Host smtp.xxxx.ca, Port 25, SSL Port 0, Connecting Domain moosehead.intelivent.ca

SMTPClient: Connection terminated with status: 7267

Router: No messages transferred to smtp.xxxx.ca (host smtp.xxxx.ca) via SMTP: The remote server is not a known TCP/IP host.

Router: Failed to connect to SMTP host smtp.xxxx.ca because The remote server is not a known TCP/IP host.

I have tried adding a DNSSERVERS entry in NOTES.INI but that does not seem to be helping.

It’s maybe a stupid question but did you try from your server command line to do this command ?

telnet smtp.xxxx.ca 25

If the command window switch to a black screen it means you’re connected (than Domino is the problem).

If the telnet command returns an error than it’s your IP config which has a problem and not Domino.

P.S. As you’re running AIX execute the command with the same user you’re running the domino server.

Thank you, That pointed me in the right direction. It ended up that our server did not have read access to resolv.conf.
