I am never ever going to attempt self-hosting email-server again. I spent 6 hours setting up all postfix, DKIM, DMARC, TLS. While doing so everything had to go wrong, like it was meant to. After those painful hours, i finally setup the webmail, and guess what? My VPS provider blocks port 25 for new customers… now i either wait for the first invoice to get completed, or use a relay (i won’t).
