  • First thing is to find out whether the messages are making it to your server, which you can do by enabling SMTP protocol logging on the appropriate receive connector(s) and then examining the logs.

    Seriously, this forum is not going to be able to solve your problem on a timely basis.  If you lack the expertise to diagnose and solve the problem, I recommend that you hire a consultant.

  • Hi,

    Have you received any NDR on sender side?

    Please confirm whether the issue happens to all external domain or specific domain (only gmail and yahoo) to narrow down the issue.

    As Ed mentioned,please try to check if you can find some related protocol log for further analysis.

    You can refer to the following article to enable Protocol Logging:
