How can I find out the file format used for an .eml file that accepts attributes in input type="file"?

Question

I am using file input html element for file upload.

<input type="file" name="data[File][0][attachment]" accept="application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/pdf"style="display:inline;width:70%% !important;" class="file-upload" />

I know this is for:

• pdf is application/pdf
• MS Word is application/vnd.openxmlformats-officedocument.wordprocessingml.document

I also need to add the .eml to the accept attribute

How to find the .eml file type?

I tried application/eml but without success.
