SendMail Does not Relay

[rakeshs859]

Hello,

I've set up sendmail to run on a AIX server to relay to a windows 2000 server. The relay was working before from this server using a different relay server ip address.

However, now it is setup to use a new relay server and it is unable to establish a smtp connection with the relay server.

I get the message:

Deferred: A remote host did not respond within the
timeout period. with [xxx.xxx.xxx.xxx]

Can anyone tell me if I need to talk with the ISP or is this something that I can try and change on my end.

I have another server that uses the same mail relay server and it works without any issues.

Thanks in advance

Hi Rakesh,

Try and telnet directly from the w2k machine to the relay and see what happens:

telnet mailrelay 25

If that does not work, try pinging it to make sure it really is reachable. It just sounds like a network connectivity problem from what you have said.

Scotty.

Thanks Scotty.

Actually, I can telnet to the W2K from the AIX server, so I don't think that is the problem.

However, how can I be sure that it is not a port problem?

Scotty,

It appears you are correct. I can ping the mail relay, however, I can not telnet into it. I believe it might be port related.

Is there a setting that I can take a look at on the AIX server?

On the AIX box do a "telnet localhost 25" and see if you get a response. If not the the problem is local, else possibly a routing/firewall port issue.
