Mail-in-a-Box is an open source software package that can easily convert your Ubuntu server into a full-stack email solution for multiple domains.
To protect the server, Mail-in-a-Box uses Fail2ban and SSL certificate (self-signed by default). It will automatically configure the UFW firewall and open all necessary ports. Its anti-spam and other security features include greylisting, SPF, DKIM, DMARC, opportunistic TLS, strong ciphers, HSTS and DNSSEC (with DANE TLSA).
