    Hello,

    SMTP mail code 5.7.1 does mean unable to relay.

    Mail relay is the process of transferring an email from one server to another for delivery. For example, if you work for Company A and send an email to someone at Company B, you connect to your company's SMTP server which then relays your email to the server owned by Company B

    That said, the issue is with the netcore mail server.

    Thanks.
