More Encryption Woes: MML/PGP uses my own key

[Stefan Kamphausen]

Dear Gnus-Community,

first: I hope I'm not being embarassing with all my questions these
days.  Please tell me, if so.

After having tested all the SMIME stuff yesterday (thanks for the
answers, I'll try to make use of them) I went into the GPG encryption
today.  I tested it by encrypting with my ID at the office to my
private ID.  Obviously they both have the same name and only differ in
the email address.

Now using C-c C-c c o inserts an mml-tag of the form
   <#secure method=pgp mode=signencrypt>
into the message.  When I then send it, it get's encrypted with my
public key from my _office ID_ so that I can decrypt it here at this
place.  Inserting another field into the mml-tag:
   recipient="Stefan Kamphausen <my@privateemail.de>" 
didnt help either.  

I didn't check whether I can decrypt it with my private ID because I
don't have that secret key here.  I only mention this because the
output buffer of mml contains some hints that that message might be
encrypted using _both_ keys. (see output below)

As always: any hints or pointers to documentation appreciated.

Regards
Stefan
