Self Hosting

When you self-host, you develop expertise in email itself, arguably a commodity service where such expertise has small return. But, you have full control and your data is your own.

The generally accepted best practice is install Postfix and Dovecot. This is the simplest path and what I cover here. But there are some pretty decent all-in-one packages such as Mailu, Modoboa, etc. These usually wrap Postfix and Dovecot to spare you the details and improve your quality of life, at the cost of not really knowing how they really work.

You’ll also need to configure a relay. Many ISPs block basic mail protocol and many recipient servers are rightly suspicious of random emails from unknown IPs in cable modem land.
