You gotta spoof the from email address. If you find an open mail relay, it’s as easy as using the send-mail command in PowerShell. I never actually did that particular kind of operation in Linux, but I would be surprised if there isn’t a cli that would do that.

Also, they likely use exchange, so if you were to spoof their email@ domain.onmicrosoft.com address, you could really trick people into thinking it was an official email from any of those addresses

Actually they’d probably do a lot better than the chickens in the industrial farms.

Isn’t it anything divided by 0 is undefined? Granted, I only have a more or less intermediate level of math, but I was always taught that multiplication by zero is always zero. But then again, zero is weird and can break my brain just as much as infinity does.
