We are always keeping an ear out for new tools, additional tools, which might be useful for family members. One which is popular is a complete e-mail package, including spam scanning, anti-spoofing, webmail and support for mobile and desktop clients.
But we are testing a more-robust platform, one which is both secure (within reason) and stand-alone to make the tasks of keeping it running more manageable. There is still some work to be done integrating it into our back ups system, learning how to utilize some of its features, and writing some user documentation.
So, stay tuned; an improved e-mail service is on its way.
