Topic: Recommended software to build email servers?
Lately, I've been interested in building my own server and I thought one of the things I could use it for is for building my own personal email server.
I'm a total beginner to this sort of thing but I appreciate it needs to have
encrypted storage for my emails and be secure against possible malware and hacking attacks, which means I should rely on libre software to build the server.
So I wonder what the Hyperbola community recommends for building
an email server, besides installing it in libre hardware like Technoethical's computers?
