New sponsors

If you use Horde - especially in a commercial environment - please consider sponsoring the project with a monthly donation. The money will be used to pay the development of new Horde features wich will be openly available to all Horde users. These type of donations are extremely valuable to the project as it allows us to continue to work hard on providing millions of users with the best possible webmail and groupware solution we are able to produce.

Each monthly sponsor will be listed here with a small image and a link to the home page. Please send the necessary details to after subscribing here.

Thank you for your support!
