T/bone SecureMail Gateway is a central, server based software solution which provides encryption and digital signatures for the entire email traffic of an organization. It works with a single organizational certificate and transparently provides its services to end users. T/bone automatically finds the certificates of external users or companies via the Internet. Secure email traffic to customers, suppliers, and partners is easily established, no matter whether or not they also deploy T/bone. Packages for Red Hat, SuSE, and Debian GNU/Linux are available for download.

With the new, major release 1.1.0 T/bone SecureMail Gateway now supports PGP and S/MIME. The powerfull certificate management and validation system of T/bone now also handles PGP certificates beside X.509 certs. Another new function introduced are "user commands": End users now can control encryption and signing of an email by putting special command patterns in the "Subject:"-field of an email to be sent. For public educational institutions like schools and universities full licenses are available free of charge.
