Backing up your email
--WEBMAIL (Horde/RoundCube/SquirrelMail)
Bringing it down from "The Cloud"
A webmail interface (Horde/RoundCube/SquirrelMail) lets you interact with data (in the form of email) that lives online. It is just showing a window to the data that is "on" our SBMS email server. When that server is switched "off", you will no longer be able to view your SBMS emails. You can, however, use HORDE's tools to download that in the form of an MBOX file, which can then be viewed by an email program that uses the .mbox data format (Apple Mail, Thunderbird, etc.).

If you usually use RoundCube or SquirrelMail to view your email, the same emails will be visible in HORDE.
