i'm aware why, but... reputable mail source chose to buy email delivery from non-ipv6 provider so they can send them at puny rate of one message every 3 seconds...? and they can't split the load over pool of ip's? this organization *MANAGES* ip space for entire european continent? they can't have agreements with large providers for whitelisting? if they chose a service instead of own employee and hw, why do they "battle" against service as if that's like single person freelance web design company everyone could just flip off since (s)he only pays 30€ / month and thereforce is unimportant small customer? also they admit they don't know how to configure spf and find that as a big hassle? and they can have like expensive beautiful office? and they somehow made ripe atlas? i have many questions!
