Encrypting to "To:" and not to "Cc:"

[Lloyd Zusman <ljz@asfast.com>]

Using the latest Oort from CVS, is there a way for me to do the
following?

Suppose I'm sending a message as follows:

  To: person@paranoid.org
  Cc: person@trusting.org
  ... etc. ...

I'd like the message to be encrypted for person@paranoid.org using her
public key (which I have in my keyring) and sent in plaintext to
person@trusting.org.  How can I set up Gnus to do this?

I know that this seems silly.  But it turns out that person@paranoid.org
and person@trusting.org are actually the same person, and she can only
decrypt her email at the "paranoid" account, which is unreliable.  The
"trusting" account has no decryption capabilities, but it's more
reliable, and so she uses it as a backup.

Even though this is less than ideal, I still need to use this method to
send email to her.  So far, I have to send the email twice, since I
don't know how to cause the message to get sent encrypted to one address
and in plaintext to the other.

Any ideas?

Thanks in advance.
