EncryptOnSend

Hello,

I would like to Encrypt mail when send it. But in case if the recipients do not have a key for UNencrypeting I would like to avoid them of these emails. Is it possible?

I was confused a little because server automatically UNencrypts email if users have not key.

from help:

To encrypt a document when mailed, this method looks for the public key of each recipient in the Domino Directory. If it cannot find a recipient’s public key, the method sends an unencrypted copy of the document to that recipient. All other recipients receive an encrypted copy of the document.
