Hi,
Spicebird is shutting down. The following is their closing down statement to Spicebird users.
Support for Spicebird has been discontinued. We thank our loyal users for all the support and recommend you to migrate to Mozilla Thunderbird for a similar customizable and open experience. Why stop further development and Support?
Spicebird isn't as relevant as it was when the project started. A few months after we started working on Spicebird, Mozilla Messaging emerged and development was active again. Many features that kept Spicebird stand out started getting introduced into Thunderbird. Thunderbird began evolving so rapidly that it was really hard for Spicebird to keep up. Where is the source code?
The latest source code is available for download (http://spicebird.org/spicebird-0.8-latest.tar.bz2), but it is based on a pretty old version of Thunderbird. It will be great if you can drop us a line about how you plan to use the source code — some of us might even help you in the new project! Is there anything else coming from here?
There are plans to push some of the Spicebird features as Thunderbird addons Contact
For help in migration check our notes on migrating to Thunderbird. For any further questions or suggestions we are available at contact@spicebird.org
