B1if store email as eml file

Hi experts,

Does anybody know how to save an e-mail as eml file in B1if 1.0? I guess it should look like that:

And the receiveemail atom would be the input for the StoreFile atom. But what Payload Type do you have to use and what would be the correct Character Encoding?

Thanks a lot for any help!

Kind regards,

Almuth
