I’d like to take a moment to say thank you to @JoshData for the time and effort put in to Mail In a Box. For me it was certainly a good start in learning to manage my own mail server with minimal effort. It’s certainly a great tool for those who want to run their own mail server but may not have a clue when it comes to managing things like DNS and webservers as well.
For me, I decided I wanted to try something different. Not because I don’t like MIAB, but more because I wanted to have a look at some of the alternatives out there. With that in mind did fire up another VPS and moved to iRedMail. Not lease as it gives a choice of backends, including OpanLDAP and a choice if WebMail clients. So I’ve given SoGo a try not least as with the OpenLDAP backend, it sports a Global Address Book, something that Roundcube is lacking.
iRedMail does not come with DNS server included, so compared to MIAB it’s a little harder to setup. But for me it wasn’t too hard. Although you do have to install certbot and provision the certificates yourself.
For ease of use, you can’t beat MIAB - it’s certainly a good start point and Josh should be well pleased with his work to date.
