Looking at S/MIME message one can see:

The data in this part has been digitally signed via S/MIME.
Message verified successfully.
Sender: 0 (user.name at example.pl)
[View Certificate]

The issue is "Sender:0" instead of "Sender: User Name". This is due to  
Polish diacritic marks in user name or surname which can be found in  
Common Name of Certificate Owner. 'View Certificate' shows "Common  
Name: 0". The certificate CA is Comodo/TERENA.

The side effect of this is incorrect import of the certificate into  
Turba addressbook where name or surname are truncated.

The certificate with Polish diacritic marks is available upon request.
