1901255 - Message forwarded by filter does not include inline images

Status: NEW

(Thunderbird :: Filters, defect)

Description

[ridethepenguin]

Attachment: Test forward 2 - no inline image.eml

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36

Steps to reproduce:

I created a filter to forwad all messages containing a particular keyword in the subject to a specific e-mail address.

Actual results:

All messages were forwarded correctly, but the messages containing inline images were not displayed correctly on the receiver's side (broken image link), as the "src" attribute of the "img" tag contained a "maibox://..." URL, which of course couldn't be resolved on the recipient's machine.

NOTE: if message is forwarded manually, i.e. by clicking the "Forward" button (which opens up an editor), then "Send", it is displayed correctly on the receiver's side.

Expected results:

The forwarded message should contain inline images (if present in the original message).

This is the same message forwarded manually, i.e. via the editor: this one displays correctly, as it contains the base64-encoded image data and its content type is properly set to "multipart/related".

Confirmed with Daily.

Just wanted to add that I'm a software developer and I'd be glad to help fixing the bug (of course, I would need directions as I've never contributed to the project and the code is not exactly trivial - I've looked at it and run it through a debugger already).
