    Perhaps you could describe how you are testing an SMTP send from the server.

    HI Lindsay_Estabrooks,

     

        Thank You for answering.

     

         I did tests using 3 different smtp servers, and i could prove SMTP because i enable the Windows smtp server and to do this test it's so simple like create file

     

    Copy the Email.txt file into the following folder: C:\InetPub\MailRoot\Pickup.

    FROM: <source email address>

    TO: <destination email address>

    SUBJECT: Test email

    This is a test email sent from my SMTP server

    I think that the "Unable to relay for ..." is directing you to the issue. Have a look at https://blogs.technet.microsoft.com/jhoward/2005/10/11/resolving-smtp-error-550-5-7-1-unable-to-relay-for-userdomain-com-error-0x800ccc79/

     

    Also, there are some great utilities out there for testing sendmail. See this: https://www.raymond.cc/blog/sending-email-using-command-line-useful-for-downtime-alert-notification/
