Well actually this is a missing feature! Since this is exactly; what the user
is requesting -> a single sided encrypted message! Otherwise I do not need
asymmetric cryptography if I force everyone to have two keys.
What is a "single sided encrypted message"?

Do you mean sending a S/MIME message using an arbitrary passphrase?   
This is not possible with S/MIME.  (And we have had support for this 
via PGP for years)

S/MIME *requires* that you have access to the other user's public key.

Getting an own Certificate, which might take days, delay an answer of email
that just need to be encrypted and send immediately. On the other hand why
should I forced to encrypt my emails in the send folder when I have an
encrypted hard disk.

As Arjen said - to send an encrypted message to someone, you need 
THEIR public key accessible via some mechanism (addressbook; keyserver).

This is how sending encrypted messages works. If you don't have access 
to the senders public key, there is no way to decrypt the message by 
the sender. Only the recipient would be able to decrypt it. This is 
why you should always encrypt messages with both the recipients *and* 
your own public key.

Two users: User1 & User2.

1. User2 import/create personal PGP/SMIME cert into Horde.
2. User1 does not import/create personal PGP/SMIME cert into Horde,
but only import User2's PGP/SMIME public key into Horde
*How* does he do this? And do the public keys show up in the 
preferences and the address book?
Sorry. Do you mean how to do the step 3?
3. User1 send a PGP/SMIME encrypt mail to User2, then error message appears.
PGP Error: Could not retrieve public key for User1@.....
SMIME Error: No smimePublicKey entry found for User1@.....
