Isn't it much easier in this case to choose a fixed subject line like
above and add anotrher header like X-Encrypted-Subject: with contains
the subject, encrypted with RSA or El Gamal? A mail reader can then ask
for the password once (or more if more secret keys are used), decrypt all
these subject lines and do it completely transparant.
