I created a little python script that took a list of domains and created various misspellings of those domains, checked for MX records set for them. I ran this on a list of "sensitive domains" (law authorities, government agencies etc). For example there were 2-3 domains for misspellings of "polisen.se" (the Swedish police) that had MX records set and were presumably receiving some emails they shouldn't.
