In Exchange 2013, is ist possible to create a Transport regex rule based on the sender name, not the sender emailaddress?
The goal is to identify fake senders, using the name field for a fake emailaddress. Normal: "John Doe " Bad: "[email protected] "
The very goal would be to identify two @ in the Sender, an exception would be, when both are the same like "[email protected] "
I'm afraid not, there's no special rule action to compare the sender name and its email address, also it's not a valuable way to prevent "fake" sender.
Instead, the SPF record will be used to declare and verify who can send e-mails from a given domain. Thus, we can use it to detect and prevent spoofing message.
