When I look at message in Thunderbird it is plain text. When I view message source I see there is only one content type:
Content-Type: text/plain; charset="utf-8"
There is not text/html part.
In the footer it has placeholder for image - [image.png]. In attachments list I see winmail.dat file (According to information in Internet this might be e-mail with attachment from Outlook sent as plain text.)
When I read the message using Rebex it returns this e-mail as Html one - HasBodyHtml returns true. Why does this happen? If we took the text version of e-mail everything would be correct but we always take Html version if it is present.
This HTML body contains inline image - IMG tag with cid:. But the file extracted from winmail.dat doesn't have Content-Disposition: inline setting. We depend on it to pass boolean Inline flag to our custom web app to display e-mails and in this case we don't display inline attachment correctly.
