Spicebird is a cross-platform email and collaboration client derived from Mozilla Thunderbird. If you are a fan of Thunderbird, but need more from it than the standard build provides, you may want to give this new bird a try.

Synovel Techologies has released Spicebird 0.4, the first public release of its open source Mozilla-based personal information manager that integrates Thunderbird, Lightning and XMPP to deliver email, calendaring, instant messaging and other communication tools on a single product.
