Could I get an off list reply from blizzard engineers. Your email system is
blocking our emails as spam, and I'm trying to resolve some geolocation
issues that disallow our mutual customers to access your services. Thank you
Out of curiosity, are you using one of those cheap dirty "misused outside of region" Afrinic blocks?
They keep trying (and spamming the crap out of a few forums) to offload them to ISPs temporarily for cheap so that the ISPs will get them cleaned up and marked as residential, then resold/abused afterward for fraud/vpn/bots.
