Well, *I* use mutt to read my email and Outlook to deal with
appointments and such on the Exchange server at work. But I'm
running NetBSD on one machine and have a WinXP box tossed in the
corner (which I get to with rdesktop from the NetBSD machine, so
that Xinerama can use both monitors on the NetBSD machine).
I can't help you much on the front of GUI mail readers, PGP/MIME-
compliant or not, since I think the Outlook interface is horrendous
and imitations only worse. (That's an opinion, not a value judgement.)

Well, don't take my word for it, but that's my memory from trying it
out some time ago. Check the documentation. (Doing crypto under an
OS that is both multi-user AND really has no way to provide secure
memory is questionable at best, though.)

Sort of. PKCS is a certificate, rather than PKI, system. The
principle being similar (signature implies faith), but it all
revolves around a single, central signer (the certificate
authority). As near as I can tell from Outlook's interface, anybody
can create a certificate saying they're anybody (they might actually
have to go to the trouble of setting those "anybody" settings within
their copy of Outlook, of course), and then other people using
Outlook will believe their certificate. That doesn't sound very
secure to me, but maybe I'm missing something about the
Also, I don't *think* PKCS really defines an encryption algorithm,
just a signing one. So it gets you half of what OpenPGP (or any
other PKI system) gets you.
