Exchange 2019 SMTP Receive Connector
Hi Tech,
We have Exchange 2019, SMTP Open Relay Receive Connector.
We have around 300+ services using this connector. Recently We engaged a few customers and performed exercise to send email with Authentication.
My question here is, How we can find which smtp connection/IP is relaying emails using authentication and which connection/IP is relaying email anonymously/without authentication.
I tried finding authentication tags in smtp receive connector’s logging without any success.
Any idea or direction to achieve this? Thank in Advance.
