An open source web-based e-mail which do S/MIME signing & encryption: IMP
( http://horde.org/imp ), development (HEAD/4.0-ALPHA) version only
though. There maybe others, too. But AFAIK all of them requires your
private keys to be stored at the server, since everything including
decryption and signing are done at the server.
