Hello list, may I pick the accumulated wisdom and experience?
any useful traffic from these subnets:
18.32.0.0 - 18.255.255.255 Amazonaws.com
$ host mail.knight-networks.com
mail.knight-networks.com has address 18.217.5.117
mail.knight-networks.com has IPv6 address
2600:1f16:b15:6902:ad0e:540b:da86:d1eb
Perhaps many, but not all AWS users are spammers.
Honest question -- are there any hosting networks that do a particularly
great job at keeping spammers away? I'd be happy to move my server.
