Ha ha ha ha ha.

I'm using Netscape 4.7. I tried with Netscape 6 and I figured it didn't

I receive the emails and everything but the signatures are always invalid.
Any chance you could send me some of the code you used to get this thing
working ?

Hang on, just had a thought - what _version_ of "Netscape Messenger" are you
using? Netscape 6+ aka Mozilla aka "nobody uses S/MIME, it's not important,
so we won't bother implementing it" aka *grrr* ... well, it doesn't support
S/MIME. You need to revert to a _useful_ email package, like the one with
Netscape 4.7 or Outlook (the only two mail packages that I know of that
support S/MIME in a graphical environment.)
