Seems worth reminding everyone that self-hosting your own email is still viable in 2021. Containerized services like mailu.io can help abstract out all the archaic configuration so you can focus on having a clean stable deployment. One caveat I would add from personal experience is that if you are running a low volume mail server, even if you have a clean IP address, you probably will struggle with successfully delivering email to a lot of the big players (like Gmail and Outlook). A lot of email service providers seem to have switched to a white-list model where they really only accept mail from know good sources. One good way to get around this when self-hosting is to relay your outgoing mail through a higher-traffic SMTP service with a good reputation. I relay all my outgoing emails from my SMTP server through Amazon SES. It is basically free for the small number of messages I send and I have zero delivery problems.
