Where do you have your mailserver hosted? i have tried to have them on OVH and Digital Ocean. but my email for hotmail and gmail ends in SPAM? MY PTR record is correct, and i have configure SPF, DKIM and DMARC, there are all passed when i come to ex. Gmail. but still ends in spam? The IP adresses i get assigned from OVH and Digital Ocean are not presented on any blacklist? I'm not sure how Google or Microsoft handle spam, but my last thought was my mail volumes wasnt high enough or it could be the hole range there are "Blacklisted" ??
