You're sorely mistaken about this. a) Spammers don't care if their crap gets rejected. At all. They will fire at anything that looks even remotely like an e-mail address. Every day I see multiple delivery attempts to mail addresses that have been disabled for years, to addresses with truncated localparts that have never worked in the first place, and even to message IDs. Message IDs! b) Just because spammers are early adopters (not only when it comes to new domains) doesn't mean nobody will ever use those domains for legitimate purposes. For instance, Google's new holding Alfabet uses the domain abc.xyz. Blocking entire TLDs is throwing the baby out with the bath water. c) Discarding mail may subject you to legal repercussions, depending on where you're located and whose mail you're handling.
