grommunio - from Zero to Exchange Replacement

In this workshop, Michael Kromer, CTO of grommunio will show (and explain) how to setup a grommunio from scratch in just 90 Minutes to be a full Microsoft Exchange replacement.


If you want to join in, please take prepared with you:

  • A domain (any domain you can play with)
  • A public IP (for simplification we will do Let's Encrypt certificates)
  • Some space for your container / VM (we will use the official Appliance)
  • Access to your DNS-Provider for your domain (Setting A, CNAME, MX, TXT records)

Michael Kromer is an IT architect and CTO at grommunio. Since 1998, he has been developing security and communications solutions for companies, government agencies, and critical infrastructure (e.g., intelligence services and the military). As a self-proclaimed nerd when it comes to firewalls, Linux, BSD, TCP/IP—and pretty much anything that contains at least one ESP32—he explains complex technical topics in an easy-to-understand, practical way and spices up his explanations with (sometimes bad ;)) humor.
