Exchange 2010 unable to receive and Send emails externally RRS feed

  • Question

  • Hi Friends,

    I bought domain from Google and registered . I can send emails internally but unable to send or receive emails from external clients or server's . Can someone explain me what changes we need to do in DNS-MX Records on google side and Exchange side . I removed Firewall as well . All ports are open (25,143,110,80).

    Thanks in advance

    Regards

  • Same issue here in Outlook and OWA? Is there any bounce message in the sender's inbox?

    Could you share more details of your environment architecture? For example, Exchange server's version build, amount and installed server roles and etc..

    Sending external messages only requires a send connector in Exchange.

    Configure Send Connector Properties

    Set the address space to * and you could send message to all external domains. Besides, better select Use domain name system (DNS) "MX" records to route mail automatically to bypass the smart hosts.

    If you have already set it up, please run the following command and send me the output:

    Get-SendConnector | fl

    Receiving external message required a public MX record in external DNS provider, we need the default receive connector to receive all incoming messages and generally no changes are required to set in those connectors.

    For details, see Configure DNS records

    If all the settings above are configured well but issue still persists, please feel free to let me know.

  • Hi

    Can you telnet to that ip on port 25 externally?

    Is anonymous ticked on the connector? Are you sending to DNS or to a smart host on your send connector?

    It is not appropriate to do that, better send the details in another post (remember to remove the sensitive info).

    Is that the bounce error when sending from Exchange to external domain?
