External web server sending email to internal recipients RRS feed

  • Question

  • Hi All,

    I have a web developer who created a web form for clients to fill out. Once submitted, the form is supposed to send an email detailing the form to Internal users as well as some external users.

    SO;

    info@exampledomain.com sends an email to two users;  dan@exampledomain.com and dan@anotherdomain.com

    My problem is that emails go out to any external domains, but not to the internal domain.

    I believe the website may be sending the email anonymously, meaning it is not authenticating with the domains mail server to send the mail.

    Our spam filter does not even see the mail come across, so it appears its not even reaching our domain. I figured maybe because it was anonymous and coming to our domain from our domain it might get blocked, but that does not seem to be the case.

    Any help would be appreciated!

  • Hi Dan

    In your Case i would suggest you to perform a message tracking for any one of the transaction that happened 

    Also i would suggest you to enable protocol logging and check the transaction in the receive connector (relay connector) if you have specified any and check the protocol logs

    Also check in the send connector protocol logs

  • Hi,

    Agree with Sathish, message tracking can help you to find where the internal emails have gone.

    The following article for your reference:

    Message Tracking

    In Microsoft Exchange Server 2013, the message tracking log is a detailed record of all message activity as messages are transferred to and from the Transport service on Mailbox servers, mailboxes on Mailbox servers, and Edge Transport servers. You can use message tracking logs for message forensics, mail flow analysis, reporting, and troubleshooting.

    Thanks.
