Make sure you can telnet to on port 25 from your exchange 
server. Even do an nslookup to verify that your dns can see it and there are no 
dns issues atm.

Subject: [exchangelist] Connection timed out

Hi guys/ladies,

  Good morning.

  Whenever I tried to send email to this particular domain users, I notice
the email would get stuck in the queue. Only after several persistent
"forced connections", then the email get out but after a few hrs, it
bounced back, saying "couldn't find the host".

  I check with the remote domain Exchange administrator and this was the
log entry

"Nov  1 18:44:59 sierra sendmail[17045]: jA22hpi17043: 
delay=00:01:01, xdelay=00:01:00, mailer=esmtp, pri=67174, [], dsn=4.0.0, stat=Deferred:
Connection timed out with".

  Anyone could provide some troubleshooting tips?

  The server is running Exchange 2003 w/ SP1, default values.

  Thank you.

  Best regards,
  Jason Tan
