Mirapoint Inc, a start-up that recently launched a dedicated internet messaging server, will announce today encryption technology for the device, licensed from the RSA Data Security unit of Security Dynamics Inc. Mirapoint will use RSA’s BSafe Crypto-C and Crypto-J cryptography components in its mail server. Mirapoint has a remote Java administration client, data from which will be encrypted along with the email messages themselves. This feature will be available with version 1.2 of the M100 and M1000 servers, available in April. Existing users will be able to download the software at that point. Version 1.1, which is out this week, adds a proxy back up feature. The Cupertino, California-based startup has just opened three office in Europe, with the headquarters in London.
