Multilevel Mail Revisited

In my posting last February, Prototyping Multilevel Mail, I discussed some techniques for  implementing an email service to support labeled zones. It turns out that a company called BlueSpace Software has done just that. They have a very cool demo showing their label-aware email client running under Trusted Extensions using the Trusted Java Desktop System. The product is called BlueSpaced TransMail Trusted Edition. Here is a quote from their web page:

TransMail Trusted Edition tightly integrates with Solaris 10 Trusted Extentions to ensure appropriate content management between the different security zones, including data labelling so that the interface operates mutliple network sessions simultanteously. 

I haven't had a chance to try it out, but I'm looking forward to doing so when it is available. 

Comments:

Some of the marketing hype is inaccurate since SecureWare had a multilevel email client way back in the 20th century. I may still have the floppies :)

Yes, I remember using it. We did some interoperability testing with SecureWare's CMW about 15 years ago.

Claims of being first are easily challenged. Sun's Trusted Solaris 1.2 had a multilevel Postmaster, which was included in its ITSEC evaluation, http://www.governmentsecurity.org/articles/articles2/Certified-Product-List.pdf_fl/Certified-Product-List-41.html
and Veridian (now General Dynamics) has a multilevel mail client for Trusted Solaris 8, http://www.gdc4s.com/content/detail.cfm?item=4b8aa8a0-808f-4e44-ada1-ff064751f74c&page=2#mail
