  • testing outbound smtp email

    I have 2 exchange 2003 servers on different sites with smtp connectors configured to talk to smart hosts on seperate DMZ.

    1 site has cost of 1

    the second site has a higher cost but i want to test it works

    if i use telnet on the exchange server and ehlo to test outbound email it says cannot relay.

    ie MAIL FROM:[email protected]

    RCPT TO:[email protected] - error can't relay

    why is this - address space is *
    authentication is off

    I have tested the smart host can send email inbound into the exchange system so that way works

    Who are you telnetting to? The Exchange server or the the smart host?

        If you are telnetting to the Exchange server and trying to send an email to an external host, then the error you are receiving about being unable to relay is what I would expect. Exchange needs to either allow relaying by IP address (not a good idea) or authentication. However sending email between servers via a smart host, smtp connector or RGC does not require ANY relaying options to be enabled.
