With the latest release of all the core modules, I did 4 tests:
#1 Send a S/MIME signed message from Thunderbird
#2 Send a S/MIME encrypted message from Thunderbird
#3 Send a S/MIME signed message from a BlackBerry 10 device
#4 Send a S/MIME encrypted message from a BlackBerry 10 device

I then used Thunderbird, IMP and a BlackBerry 10 device to check the messages.

On Thunderbird
No problem with any of the messages. They are identified as signed or  
encrypted and are successfully verified/decrypted.

On IMP
- Signed message #1 shows this error message: "Message verified  
successfully but the signer's certificate could not be verified". The  
certificate is in the addressbook and the public key is stored in IMP  
though.
- Encrypted message #2 is successfully decrypted.
- Signed message #3 shows this error message: "Verification failed -  
an unknown error has occurred.". The public key is not in the keyring  
and IMP doesn't offer to install it (but that could be because of a  
problem with Turba's default addressbook)
- Encrypted message #4 shows: "Could not decrypt S/MIME data.". No  
error in the logs.

On BlackBerry 10 device via ActiveSync
- None of the messages are identified as SMIME as far as I can tell
- Encrypted message contains an attachment which is detected as a   
"MIME Encrypted Message" and there is a green "tick" indicating it's  
valid, but when tapping on it, the device indicates that there is no  
viewer for it on the device.
