IIS SMTP relay cannot send e-mail to our own domain. RRS feed

  • Question

  • Hi,

    we installed SMTP Relay with IIS for Microsoft 365. When I try to send e-mail from the printer or some devices the test mail does not deliver to the target domain even our own domain. But for some domains, it works.

    I couldn't find the reason of this issue. Hope someone can help me.

    thanks in advance
