I self host a mail server too. Static IPs are not available for a residential connection where I live which makes PTR and SPF records hard. What I've been doing is using Oracle's "always free" VM to host VyOS as an ingress/egress router. It's been pretty easy to set up the mail server itself using iRedMail.

I've had some problems with spamhaus and outlook because that whole IP range is not trustworthy but otherwise it's just worked (Spamhaus was nice enough to put me on a whiltelist).

I know hosting at Oracle is not moving away from US cloud services but I set this up two years ago and this could be achieved using any cheap or free VPS.
