When I was 12, I learned about open SMTP relays and how to spoof email this way. I once spoofed an email between two rivals on a community I was a part of and started a flame war.

Good times.

When I was in high school in the mid 2010s, Verizon's email-to-SMS gateway didn't verify SPF/DKIM/DMARC, and I had a field day showing my classmates the Viagra ads that Hillary Clinton's "hacked" email server was sending me. In reality, it was an open relay, but Verizon didn't care; they always delivered it anyway.

I once made an enemy on AOL and he was a spammer--he put my email in the from: field and I got a lot of hostile emails.

But the joke's on him--it led directly to me meeting a lifelong friend & mentor.
