While Mail-in-a-Box is easy to use, it is still a complex piece of software. Be sure to read the documentation and take steps to secure your email server, including regular updates and backups.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
