I once worked somewhere where someone emailed 10k people (the whole org) a document that they shouldn't have. Then hundreds of people replied all "I don't think this is for me", then hundreds more replied "please stop replying all". The email server was locked up for hours, no one could email anyone as it worked through the backlog delivering millions of emails.
We had a private company email server wayyyy back in web 01, the pasty chef and I copied our outbox emails (literally one click, "select all" and forwarded them to the restaurant chef who was on vacation. He was not happy when he came back after a few weeks to find tens of thousands of unread emails.
