@SpaceLifeForm@infosec.exchange Thanks, instead of regional, perhaps its ISP based. Our email was blacklisted as "spam" by the Spamhause corporation the second it came online. I suspect there are some ISPs/ DNS servers who have done the same. My guess would be our name.

@anolandria@mastodon.social A logical conclusion unfortunately. Remember, DNS over UDP is not secure and easily MITM-ed by your upstream ISP(s).
