THEY always tell you it is too hard and too complicated to run your own mailserver. Well, that's a lie. In this video we are going to set up our own mailserver. We discuss reasons to do that, prerequisites, recommendations, security, the actual installation process, setting the required DNS-entries (including DKIM, SPF, and DMARC), setup of mailboxes, and what to do after the installation. This video is a bit longer, but this is time well spent if you want to run your own mailserver! Please apologize the sound quality - I had some issues with the microphone. :-( Resources: GIST with firewall commands: https://gist.github.com/opentaq/2ce85108bee528700477c6db89610968 Mailcow Documentation: https://mailcow.github.io/mailcow-dockerized-docs/ Chapters: 00:00 - Intro 00:36 - Why running your own mailserver? 02:59 - Prerequisites 04:32 - VPS- / VM-Setup 08:17 - Securing the System 10:57 - Reverse DNS 11:51 - Basic DNS 13:49 - Installing the Mailserver 16:10 - Changing the Admin-Password 17:09 - Adding a Domain and Finishing the DNS-Setup 24:05 - Adding a Mailbox 25:38 - Checking the Configuration 27:29 - Using the Mailserver 28:45 - What's Next? 30:28 - What do YOU think?
