From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I use Mailcow and it works well. Easy to configure, and it uses Docker so it's self-contained and very easy to move to a new server if you ever need to do that.
I'm using an SMTP relay for outbound emails, though. I didn't want to have to deal with IP reputation issues, especially with Microsoft/Hotmail. I'm hosting my server on a VPS, and spammers in the same subnet can result in the entire subnet getting blocklisted. Configuring a relay is easy in Mailcow's UI, and can be configured per domain.
