3. If you run your own MTA, I highly recommend blocking all ~1000 junk gTLDs and punching specific holes in those blocks only for the domains that you want to receive email from. For small to medium sized operations, this works pretty well. (Do remember to exempt postmaster@, abuse@, etc.)
Is there a good one-per-line list of those gTLDs? I'll have to figure out where to shoehorn that into Zimbra 8 (shut up), but it runs over Postfix, so...

That is a list of all top level domains. I suspect that’s not what Jay was looking for. Something scraped out of https://newgtlds.icann.org/en/program-status/delegated-strings may be closer. Regards, -drc
