A Reddit user known as Meta4X has decommissioned a self-hosted Microsoft Exchange installation that began with Exchange 5.5 on Windows NT 4 in 1999, replacing its final role as a network alert relay with Postfix on Ubuntu Server LTS. The user had already migrated mailboxes and email delivery to Microsoft 365 a couple of years earlier, keeping Exchange around only for internal alerting. Over the decades the setup was upgraded through Exchange 2000, 2003, 2007, 2010, 2013, 2016 and 2019.
