If I had a clear concept how to identify bouncing emails I could provide a script I wrote for $.

But this would also imply the need for disabling and reactivating an address.

This would cause much traffic

Only if everyone did it, and then at a high rate. I would figure refreshing (automatically) once ever 15 minutes would suffice, and not cause much hurt to the server.

Does that make sense?

Don't know, I was basically following tye's reasoning.

update

I'm aware that the CB Sidebar somehow contradicts the traffic argument.

With JS, the tab does not need to be in front of you. You can be doing something else when an alert of some form of message pops up.

Ah, I see.

FWIW, you can also poll the private message xml ticker ticker, be it in JS or anything else.

That's what I get (excerpt)
