I occasionally check my unrouted mail inbox, which usually contains a bit of junk sent to an unused mailbox. Today I found over 2000 items in there - all of it bounced from othe undeliverable mail addresses. ost of it was sent today, and its still arriving at a regular rate.
I have now discovered I can send unrouted mail to a 'blackhole'.
