Years ago, it seemed really cool to be to say "sure, anything @______.com goes to me, pick a username", and I tried doing some light "spam tracking" tagging, but now it's a mess with 10K+ spam messages (including dictionary-ish guessing games) going all to my one gmail account, not to mention all the bounces from "Joe Jobs" where these jerks send spam that seems to be from my domain.
Any advice for figuring out what email addresses are in use? I kind of wish gmail offered some sort of data mining method to show me what my top aliases seem to be for non-spam messages. I hate the idea of losing contact with people and organizations who might be using an obscure alias."
