      We have our SPF protection setup on our DNS system and that's working fine. I even have it where all external emails have a giant red warning saying that it's external, but I still get users asking us if spoofed emails are legitimate. The spoofed email addresses nowadays looks something like [email protected]. Our emails are always just [email protected], or something similar. I know for a fact people are responding to the fake emails. Do you guys know of any way I can finagle a O365 rule to quarantine any email addresses that have our domain in the local-part?

        That won't address your primary case of gmail addresses, though.

            Actually that might work. If the sender is outside the organization and the sender address includes our domain, just put in junk. I'll test this out tonight and see if it works right. Thanks!
