Steps to reproduce:

Attacched a text file with fixed lenght lines (1900 byte each terminating with CR LF).
(thunderbird version 78.9.1)

Actual results:

Sent file is corrupted. The source of the message sent contains extra spaces (ASCII 20 after the = sign) at EOL making the file not usable.
With version 78.4.3 the file was sent correctly.

Expected results:

Not adding extra spaces

Where and how did you check the sent file? In Thunderbird's outbox?

Comment 2

[alfredo.nobili]

No, both in sent item folder. The recipient confirmed that the file is corrupted.

Just to avoid misunderstandings: You successfully checked that your attached file is already corrupted in your own local Sent item folder?

Attacched a text file with fixed lenght lines (1900 byte each terminating with CR LF).

How do you manage to send that attachment quoted-printable encoded? If I try to do so, it always gets base64 encoded.

Sent file is corrupted. The source of the message sent contains extra spaces

Those spaces are not realy extra spaces. The last line is therefore proportionally shorter.

(ASCII 20 after the = sign) at EOL making the file not usable.

But here they are actually wrong, because TB creates a line break from it when saving.

If I set in about:config the flag mail.file_attach_binary to true I get a base64 encoded attachment. With the default value (false) I get a quoted-printable encoded .

This bug should be closed after bug 1689804 was backed out from ESR and the issue was fixed on beta by bug 1702197.
