Hello,

A quick question to which a quick search didn't reveal an answer: how does ASK handle spam that comes from invalid addresses? Does/can it attempt to verify if there is a registered MX, or does it just fire off the confirmation message (thereby using as much bandwidth as bouncing identified spam, generally thought to be a bad idea)?
(NB: I'm talking about the host part only, not the username part.)
