T/bone SecureMail Gateway now supports PGP certificates

T/bone SecureMail Gateway is a central server-based software solution that provides encryption and digital signatures for email traffic in an organization. It works with a single organizational certificate and automatically finds the certificates of external users or companies via the internet. With the new major release 1.1.0, T/bone now supports PGP and S/MIME certificates, and introduces a new function called 'user commands' that allows end-users to control encryption and signing of an email by putting special command patterns in the 'Subject:' field. The press release also mentions that full licenses are available free of charge for public educational institutions like schools and universities.
