Attached file Email Source.txt

Steps to reproduce:

Receive email (see attached page source)

Actual results:

Subject line shows as:
``

Expected results:

Subject line should be:
Weekly market update + Growing the value of bp

See attached screesnshot of subject line. The ? character didn't come through in the bug report.

The header in the attached message source is Subject: Weekly market update + Growing the value of bp. It's close to impossible that this is displayed as the UTF-8 replacement character <?>. For the developers to take closer look, you should save the message as .eml file and then attach it after removing any personal information.

Copied txt of file into mbox file and I'm seeing no issues.

Try this:

  • Settings > General
  • scroll to bottom and click on 'Config Editor'
  • In search type: mime
  • look for: mail.strictly_mime
  • click on far right toggle icon to chnage from 'false' to 'True'

Do the same for : mail.strictly_mime_headers

Restart Thunderbird.
REport on results.

In Config Editor - after entering the search : mime
It might be of use to post an image of contents, so we can see the carious mime results.

The advice from comment #3 is not correct. Pref mail.strictly_mime determines whether bodies are encoded using quoted-printable upon sending. Pref mail.strictly_mime_headers is dead. Changing the prefs won't change the display of a message, neither headers nor body. (The same incorrect advice was given in bug 1880892 comment #3).

Attached file Sample email

I've attached a sample email exhibiting this problem, however, when i re-import this email into Thunderbird the subject line is fine, so it's not easy to reproduce.

Since I reported this issue I've seen the issue a second time, and re-importing the email in Thunderbird also works.

This is happening in an IMAP folder with TB 124 beta? What happens if you repair the folder? It looks more like folder corruption (bug 1872849) than an encoding issue in the subject. As I said, there is little chance that pure ASCII subjects are displayed badly.

Repairing the folder did indeed fix the issue 👍
