My application polls a specific email account and downloads email attachments to disk. I am able to successfully handle inline email attachments and outline attachments as parts (Part instanceof javamail Part).
But, there's one specific email wherein it has an attachment that is of type com.sun.mail.util.BASE64DecoderStream.
Hence, I am not able to fetch the file name or its inputstream. Although, i can see the fileName in original message headers.
Following is the snapshot of the headers:

Please assist, how to fetch the filename and get input stream and thus save it to disk as file.
There's no attachment in that message. It's a single part (as opposed to multipart) message of MIME type "application/pdf". Since a MimeMessage is-a Part, just treat it the way you do an attachment Part.
