Second Exchange Server not able to receive mail

Posted on 2009-02-22

I have installed a second Exchange 2003 server into my exchange organisation. Default install and I've changed its SMTP Virtual server to match the settings on the first server.

I've created a test account and moved it to the second server and encountered a strange problem. I can send email from this account and when tracked it gets routed through to the first server and sent. However when I send email to the account from either internal or external it doesnt go through and sits in the queue of the first server with the following message "The remote server did not respond to a connection attempt"

Neither machines are firewalled from each other, both machines can ping each other, both machines can telnet to port 25 of each other.

So pretty much new server can send mail but not receive.

Any suggestions?

    They're part of the same routing group?

    Check you can open TCP Port 691 between the servers
    Check the "Microsoft Exchange Routing Engine" service is running

    Lets start with this...

    "SMTP Virtual server to match the settings on the first server"

    What exactly did you change?
    You shouldn't need to change anything for email to flow.

    Have you set a smart host on the SMTP virtual server? If so then that MUST be removed and replaced with the smart host on an SMTP Connector.

    Thanks for all of your suggestions. Found out what it was, previous IT administrator had the first servers SMTP Virtual server assigned to port 26 for some reason.
