Set Alert notification when sender e-mail address and reply to e-mail address are different
Hi There, Our company would like to set an Alert or some kind of notification to end user when sender e-mail address and reply-to e-mail address are different to avoid spoofed e-mail address ...
Detecting spoofed messages is not as easy as that. Explore the features we have available as part of ATP if you havent done so already, those inlcude tips that notify the user when the anti-spoof checks fail: https://docs.microsoft.com/en-us/office365/securitycompliance/anti-spoofing-protection
In addition, you can also add a transport rule that prepends messages sent from external parties with some warning text, or change the message subject, etc.
