Bitwarden & PurelyMail for me.
I'm using PurelyMail with my own domain but frustratingly emails from my homelab are being blocked by apple.
I guess it's the reputation of my Domain? I've setup SPF, DKIM and DMARC but no dice.
I've (recently) started using Cloudflare for my nameservers so thinking about setting up their DMARK and possibly even move my Domain over to them from IONOS. If it makes any difference, who knows.
