[MlMt] Cannot Send S/Mime Mail

[Jan Vanvinkenroye]

Hi!

I am setting up S/MIME Mail encryption. I have acquired a certificate 
and have installed
it in the keychain. In mail.app sending and receiving mail is possible. 
In Mailmailte
i get the error „Unknown format in import. Error code: -25257“.

What can be the next steps?
