Dear Mr. Bernier,
Many thanks for your contribution to this topic. It is an indirect reminder of how desperately email needs an easier-to-use encryption capability.
I would dearly love to regularly use encrypted mail, and think I might just manage to get my Windows head around the Linux techniques you detail. However, I fear few of my correspondants would be so lucky.
Market opportunity for the Open Source Community: simpler GUI access to encrypted email. If I appear to seek "burger flipping" solution to a "rocket science" problem, guilty as charged.
Links to such projects, FAQ and HOWTO welcome.
