خالد حسني أَنَا الّذِي نَظَرَ الأَعْمَى إِلَى أَدَبِي وَأَسْمَعَتْ كَلِمَاتِي مَنْ بِهِ صَمَمُ

I built an Arabic language pack for Thunderbird 2.0.0.9 (originally based on Arabeyes translation, but completed and revised).

It can be downloaded from here. Feedback is welcomed.

Update: I've updated the file several times, to fix various problems, since this post, please download it again.
