There was a time when overnight I received 200 copies of an email in my inbox. The emails were sent manually, typos, delays and all. Very industrious individual. I was discussing this with a colleague of mine the next day and it transpired that they'd recently taken delivery of two DEC Alpha workstations. They were both sitting on his desk, being configured for actual work. We set up a system using .forward files where DEC Alpha 1 would forward an email to DEC Alpha 2. On DEC Alpha 2 we set up the same in reverse. We sent an email to DEC Alpha 1 and CC'd in our individual. We let it run for 5 seconds. In that time the two workstations, doing nothing other than sending email, managed a combined 25k of messages. We never did hear from that person again. These days when I think back about that, it was probably one of the early DOS attacks. We were a little shocked how well it worked.
