cannot open encrypted *.eml files - [Portions of this MIME document are encrypted with a Notes certificate and cannot be read.]

The following message appears when opening an *.eml file, which was saved before from an encrypted email.
[Portions of this MIME document are encrypted with a Notes certificate and cannot be read.]                                                   
Steps to reproduce:                                                    
1. open a new memo                                               
2. send memo to yourself or another recipient with encryption flag     
3. open the email (you will see everything)                            
4. save the email as *.eml file (File >> Save as)                      
5. open the *.eml file                                                 
6. the error occurs (in standard and basic configuration)             


Need some solution to save the encrypted email and shared with other users.

    The EML file must contain the unencrypted email (eventually with a warning). Some of my colleagues lost emails, not knowing that the feature was buggy (or badly designed).

    This is confusing for users, they can read the message in mailbox, they save the message to .eml (without any warning that this is potentially useless), open it again in Notes but the software is not able to decrypt it. I would understand that some other mail client shows the encrypted info but within Notes you where you have your private key should be able to read it again.

    The email you are looking at is encrypted. Exporting this email means that you are exporting an encrypted email, where of course the body is encrypted in the *.eml file.
