361040 - Emails with embedded images sent via org.commons.mail are not shown

Status: RESOLVED INVALID

(Thunderbird :: Mail Window Front End, defect)

Description

[Przemyslaw.dul]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.0.8) Gecko/20061025 Firefox/1.5.0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.0.8) Gecko/20061025 Firefox/1.5.0.8

Emails with embedded images sent through the org.commons.mail api are not correctly displayed in thunderbird, but in outlook or the web-email-frontend of gmx.
I am not sure if that is a thunderbird problem or probably an org.commons.mail (or the underlying javax.mail) problem. On the other hand outlook can handle such sent emails.


Reproducible: Always

Steps to Reproduce:
1. Run the code, sent mail
2. display the email through thunderbird and other clients


Actual Results:  
Thunderbird shows neither the embedded image nor the text!

Expected Results:  
same result as outlook or web based clients.

The MIME structure of that message is completely wrong.  It is:

Top:  Content-type: multipart/alternative        <-- wrong
 Part 1:  Content-type: text/html
 Part 2:  Content-type: multipart/related        <-- wrong
  Part 2.1:  Content-type: image/jpeg

It should be:

Top:  Content-type: multipart/related
  Part 1:  Content-type: text/html
  Part 2:  Content-type: image/jpeg
