The IP address sending this message does not have a PTR record setup

    Question

  • Hi Experts , 
    Get-SendConnector shows me the following 2 send connectors:
    EdgeSync - Default-First-Site-Name to Internet {smtp:*;100}  True
    EdgeSync - Inbound to Default-First-Site-Name  {smtp:--;100} True

    Is this default connector which gets created by default ? Please advsise 

    We send the emails to internet directly without smart host. We have recently saw an issue where emails send to the *@gmail.com were not delivered with the NDR : The IP address sending this message does not have a PTR record setup. As a policy, Gmail does not accept messages from IPs with missing PTR records. Please visit https://support.google.com/mail/answer/81126#authentication for more information. g8si1635946otb.321 - gsmtp 

    The command to remove the message headers needs to be run on which send connector
    Get-SendConnector "XXXXXXX" | Remove-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights ms-Exch-Send-Headers-Routing

  • Thanks I am looking at the send connectors configured and want to change them now  , 

    Get-SendConnector shows me the following 2 send connectors:
    EdgeSync - Default-First-Site-Name to Internet {smtp:*;100}  True
    EdgeSync - Inbound to Default-First-Site-Name  {smtp:--;100} True


    Under the Network settings:Specify how to send mail with this connector.MX record associated with recipient domain is checked. I want to know the difference between the 2 connectors Default-First-Site-Name to Internet and Inbound to Default-First-Site-Name . Are they both needed ? If I want to relay all outbounds through the smarthost do I need to create a new connector . If yes what happens to the Default-First-Site-Name to Internet

  • Hi,

    As above mentioned, those connector was be created after deploy EdgeSync.

    The Edge Subscription creates the following Send connectors:
    A Send connector named EdgeSync - Inbound to <Site Name> that's configured to relay messages from the Edge Transport server to the Exchange organization.
    A Send connector named EdgeSync - <Site Name> to Internet that's configured to relay messages from the Exchange organization to the Internet.

    More details about it, refer to: Send connectors created automatically by the Edge Subscription.

    Thus, if there's no Edge server or EdgeSync any more, you can remove those connector, and create a director send connector to Internet. 
    For your reference: https://technet.microsoft.com/en-us/library/jj657457(v=exchg.160).aspx

    To fix your issue with PTR record, please contact your ISP to add it.

    Best Regards,

    Allen Wang

  • Hi Allen,

    What emails will be send using both the connector . I can understand EdgeSync - <Site Name> to Internet will send emails to the outside world over the internet

    What about the EdgeSync - Inbound to <Site Name> that's configured to relay messages from the Edge Transport server to the Exchange organization. Is this for internal mailflow within the exchange server oraniozation.

    Please explain
