the .eml file is empty.
in the "sent" folder it has content while it's empty for the receiver.

Have you checked if the .eml file is actually empty? It shows as "0 B" in K-9 Mail, but otherwise should contain all data.

Hello. I've checked it. The file is not really empty. When we open it, it shows the content and it's not empty. However, the email display screen only shows the size as 0. While it's not really zero, it does contain content.
Now, considering this, I think we should fix the issue of the size being shown as zero. Am I right? Do you have any thoughts on this?

ups, I checked and then forgot to answer. I wanted to check and compare/hash the files on desktop first. I will do that now.

I debugged. Actually, on the receiving side of the email, the field size(attachment.size) of the .eml attachments is zero!!
Do you have an idea to fix this problem? that we can find and display the real size of those attachments? @cketti

I continued debugging and examined the code in more detail. I realized that even on the sender's side, if the database is cleared once after sending the message and we try to reopen that message, it also shows a size of zero (on the sender's side)!!

Confirmed. Ditched Thunderbird because of this one because it hasn't been fixed for over almost a year now and I can't use a mail client negleting such basic features for business purposes.

I am unable to reproduce this 0 B issue both from sender and receiver (both F-Droid Thunderbird), the size is correctly displayed.

This visual glitch is still happening on K9 19.2 for me on any e-mail

@Benjamin-Loison could you maybe log what steps you are doing or record them in a video? (without leaking private emails)
Alternatively take a screenshot of the email on the receiving F-Droid Thunderbird instance :)

@Djfe

If it can help I am on Fairphone 4 LineageOS 23.2 Thunderbird 19.2 and the email address provider is @orange.fr.

Screenshots:

I don't repeat last 2 screenshots being identical in outbox as in inbox.

I can provide more details (if you specify me what details you want) if needed.
