Over the past month or so I’ve been trying out running my own email server. This has come about due to warnings from Mailchimp giving warnings about our newsletter emails potentially being marked as spam because we used a Gmail account and they could not verify the domain or identity of our email address. Thus the desire to try one of these self-hosted solutions that I could potentially use for friends and family needing email. Obviously I could have gone with a hosted solution and just setup my DNS per Mailchimps requirements, but what is the fun of that.
My first choice was using mailinabox.email which runs well and is fairly easy to setup. It consists of Postfix, Dovecot, Z-Push, Roundcube, ownCloud, Spamassassin, Postgrey, Nginx and runs on Ubuntu 14.04. I opted to run this on Digital Ocean. The server handles all DNS for the domain you specify as the root domain to handle your email. It allows you to also setup many domains on the server with unlimited users, issuing of Let’s Encrypt certificates, etc. For me a couple of things were lacking in regards to user management. Mailinabox website recommended two other platforms that had a little more advanced feature set so I checked them both out. I chose Modoboa I honestly liked the admin and user interface and management a little bit better as well as the statistics for traffic and spam.
