Title: added support for other multipart types than "mixed"

We need to send HTML-Emails that have a plaintext alternative for clients that do not allow/suppress HTML content. The original postal version always used type "mixed" for the multipart, which caused both text and HTML bodies to be displayed. So we added a check for an optional keyword at the beginning of the sequence of body parts that causes another multipart type to be set if present. (See example in README.md)
