Couldn't you just setup a domain with an email hosting provider and then turn on catch-all for that domain? For me I can just use any email @my-domain and it will be forwarded to my actual email address.
Yes, you can do that. But if you run your own server you can configure more complex filters to handle situations where mail is flagged - discard loudly (telling sender), discard silently, move to special folder if unsure of spamminess, let through.
Then you start getting an amazing number of emails to alice@yourdomain.com, bob@yourdomain.com, chris@yourdomain.com, dan@yourdomain.com, ceo@yourdomain.com, sales@yourdomain.com, etc.
