Please don't make the mistake of comparing Ruby to Rails. Ruby is a language, Rails is a framework implemented in that language. Also, Ruby is not "new" (it's older than Java), but it is fun. Your implication that that makes it unsuitable for "large-scale" or "high-traffic" sites is, however, completely specious.

One of the worst things, though, about having a "catch all" address on a domain, is that you receive all the bounces from forged spam that's using your domain.

I get tons of bounces from spam to things like: jsdjfqwnc@[mydomain.com].

Luckily these are relatively easy to filter, but are superbly annoying. Why do these spammers pick on my and my little, innocuous domain?

Worse, every once in a while because somepeople don't understand that from headers can be forged, I get on a blacklist, so my mail can't get to places like AOL, etc.

Is there any cure for this?
