Subject Re: Using Tesseract OCR to extract PDF files in EML file attachment
Date Tue, 04 Apr 2017 13:12:36 GMT
You'll need to use something like javax mail (or some of the jars that 
have been built on top of it for higher-level access) to open the EML 
files and extract the attachments, then operate on the extracted 
attachments as you would any file.

There are alternative, paid, libraries to parse and extract attachments 
from EML files as well.

EML attachments will have a mimetype associated with their metadata.
