I host my own email. I'm not permanently marked as spam/blacklisted. Although it takes a fair bit of tedious setup and configuration to get it to work right. And every now and again a blacklist site will mark my domain temporarily when it detects that some server in my IP block is acting suspicious. This mainly happens because I host on a VPS. The only problem with email self-hosting is just how many moving parts are involved in a typical setup if you're using tools from unix-land. You need many different programs to work together in a typical setup: - postfix - dovecot - spamassassin - fail2ban - kerberos - ssl+tls - etc.. And you have to know about how unix account security works because some of the older programs haven't been updated to use modern authentication mechanisms and so they need to be isolated and carefully managed, etc. The other problem is DNS/verification. You have to set up your DNS records with arcane configuration options that are not well documented in order to play along nicely with the email community and not get blacklisted/blocked. Some projects have popped up to try and offer containers that have everything pre-configured. ymmv.
