In college I had to write a program to send emails. This was around 2012. Basically we had to send the low level commands of an email for it to go through. After doing this I realized something weird. The email gets to say who it is from. There are obviously ways to sign the message and verify it and most email servers block messages that don't have these because of how trivial it is to fake. It's basically like putting a name tag on that says "Joe Biden" and everyone believing you're the president.
I didn't do anything malicious but I did mildly prank my girlfriend. I don't remember what I did but I'm pretty sure I told her before I did it. I really didn't want to end up getting expelled for """hacking""" so I didn't do anything remotely bad. The irony is the assignment wouldn't have worked and been as interesting if my campus had the proper security measures to block the messages.
It could be that the web client for our email mentioned something about the sender being unverified and not to trust it but I don't remember.
I tried to send a message to support for a company with a form on their website. I got an email back saying it didn’t pass SPF because they used my email address in the From: header.
I did manage to find the email address their PHP script tried sending it to. I emailed them about the problem with solutions to fix it. And of course they never got back to me.
If email were invented today people would complain about how complex and annoying it is to sign up.
