Best Practices - Sending Javamail Mime Multipart Emails - And Gmail

Solution 1:

Solved! It seems according to the multipart MIME spec, the order of the parts are important. They should be added in order from low fidelity to high fidelity. So it seems GMail follows the spec and uses the last part. In my case I had them HTML, Text. I just swapped the order to Text, HTML and Gmail renders it correctly...

i.e.

MimeBodyParttextPart=newMimeBodyPart();
textPart.setText(text, "utf-8");

MimeBodyParthtmlPart=newMimeBodyPart();
htmlPart.setContent(html, "text/html; charset=utf-8");

multiPart.addBodyPart(textPart); // <-- first
multiPart.addBodyPart(htmlPart); // <-- second
message.setContent(multiPart);

Thanks for the help!
