I'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.
