The hosted system will be provide web-based email to 15 secondary schools and 125 primary schools across the region and provided the best total cost of ownership, according to Giles Nunn, Carmarthenshire County Council ISP officer.

The new system will reportedly be based on Debian, the GOsa PHP-based account management tool and the Squirrelmail email client and represents the latest in a series of UK projects announced recently by Sirius.

In August it announced that it had started a project to move Kings College School Cambridge to build a Linux-based email and proxy filtering network solution, while in July it announced that it was providing technical support to the BOC Group for a knowledge management system based on WikiMedia.
