Since new update spam images rendered inline

Post by whyuseusernames »

Not sure what changed, or if a default setting flipped, but a few months ago, maybe longer, thunderbird updated and ever since then i have been getting spam in a particular way that i never got before. Basically, there are like attached images? or something? and they are rendered instead of just being attached. I thought it was "display attachments inline" but turning that off made no difference.

Before i think they either didnt render or came as attachments, not sure, but i never saw graphic spam images like i see now. i have all external links off, the image is inside the email, base64 encoded. But im not sure if thats how every images appears in the source. probably. I have attached an example image as well as the code i think makes the image work. Is it an exploit or is it a feature i can turn off somewhere? i dont want to go to pure text based email, as that makes everything messed up generally these days, but maybe that was the setting that got flipped? i dont know.. i cant keep track of all the changes in software with developers screwing with things...

aw crap i cant figure out how to attach a file to this post.

here are some code snippets

Hello Why......?
For reference on posting images here...

http://kb.mozillazine.org/Posting_a_scr ... _the_forum

Just be sure to remove any personal info.
Reduce the images to around 600 x 500 in your favourite image editor.
Use any of these Hosting sites...

> https://imgbox.com/

Then...
Select the code listed as "Forum Thumbnail", copy the code and paste it in the thread where you report your problem.

The mail.inline_attachments pref can show or hide attachments of supported types rendered directly in the message body view. (e.g. JPG, PNG)

The mail.inline_attachments.text pref can show or hide text attachments. (e.g. CSV, HTML, TXT)

* mail.inline_attachments (default true)
* mail.inline_attachments.text (default false)

The mail.inline_attachments pref works the same for me in the Inbox folder and Spam folder with the Google IMAP account.
