Trustedbird is an email client based on Mozilla Thunderbird.
Two branches are currently available:
⇒ Trustedbird 3.1 which is based on Mozilla Thunderbird 3.1.x with the following additional features:
⇒ Trustedbird 2 which is based on Mozilla Thunderbird 2.0.0.x with the following additional features:
- Enhanced Security Services for S/MIME (RFC 2634)
- DSN (Delivery Status Notification) ⇒ the backend is now integrated in Mozilla Thunderbird 3.
- SMTP PRIORITY extension
- Secure Headers / SASL EXTERNAL (for XIMFMAIL add-on)
Note: Trustedbird is a temporary fork of Thunderbird in order to test some new features before being integrated into the official Mozilla Thunderbird.
Language packs (optional)
Trustedbird is currently only built for the i386 architecture (32-bit). Current packages have been tested successfully on 64-bit systems (Debian Lenny amd64, Ubuntu 9.10 amd64 and Windows 7 64-bit) with 32-bit libraries.
In order to run Trustedbird on 64-bit Linux systems, you must install the 32-bit compatibility package.
With Debian/Ubuntu, install the ia32-libs-gtk package:
# apt-get install ia32-libs-gtk
As Trustedbird Debian package is for the i386 architecture, you must force the installation on the amd64 architecture:
# dpkg -i --force-architecture trustedbird_x.y.z_i686.deb
