Call MimeMessage.saveChanges() on the enclosing message, which will update the headers by cascading down the MIME structure into a call to MimeBodyPart.updateHeaders() on your body part. It’s this updateHeaders call that transfers the content type from the DataHandler to the part’s MIME Content-Type header.

Time to answer my own question. This is a really old question and it probably wasn’t possible at the time but lots has changed since then.

E-mail messages An e-mail message consists of headers (e.g. “From”, “To”, “Subject” etc.) and body (see RFC 822, section 3.1). The body of the message is, by default, treated as plain ASCII text. MIME (RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049) defines extensions which allow specifying different types of email content. One … Read more
application/vnd.microsoft.portable-executable is a registered MIME type and its description matches what you want to use it for. The x- prefix in application/x-msdownload indicates that it is experimental so it should generally be avoided: Especially if something standard is available as it in in this case. application/octet-stream is for arbitary collections of bytes. It does match … Read more
