How to configure a small mail server  

This post is about setting up a mail server on an Internet facing host. It will accept and send mails for a domain, store the accepted mails locally and deliver them using POP3. This is a rather lengthy post because there are quite some pieces to put together. OpenSMTPD will handle incoming and outgoing mail using SMTP. rspamd will support it in fighting incoming spam and malware (using ClamAV), and signing outgoing mail using DKIM. Dovecot stores received mail for users and deliver it using POP3. Finally acme-client(8) is used to manage the certificate from Let's Encrypt.
