Although he's wrong on the everything@domainI'm been on the receiving end of bot nets doing precisely that many times. Most obvious when diverse bits work through in alphabetical order. Although most only went through Firstname@, although some tried firstnamesurname@ and variations.
I did actually tell him that you will get emails for tom@ and john@ - even if you've never given out these addresses. And I have also seen someveryoddstring@ getting a fair amount of spam - I've always assumed this was caused by someone increasing the quantity of a list of email addresses by adding some fakes.
But I don't remember ever seeing (or hearing about) a botnet performing an actual dictionary attack on a domain. It's just not worth it.
So if you use yourbank@youdomain, and you get spam sent to the address, you can be certain there is a 'leak' somewhere.
