Description
Checklist
- I have used the search function to see if someone else has already submitted the same bug report.
- I will describe the problem with as much detail as possible.
App
Thunderbird for Android
App version
13.0
Where did you get the app from?
Google Play
Android version
Android 16
Device model
Pixel 10 Pro
Steps to reproduce
Send an email with an attachment, note that it reports not sending.
Check the email you sent it to - note that it DID send.
Go back to thunderbird, see that the email is still in the outbox and that you have a notification locally of the failure.
This reproduces on my Fastmail account nearly 100%
Expected behavior
Emails that sent should not be reporting that they didn't send. Emails with attachments should send properly.
Actual behavior
Emails with attachments report failing to send, but in fact do send.

Research direction
No source file or test is named in the report; first reproduce the attachment-send flow on Thunderbird for Android with Fastmail and inspect the send and outbox failure handling. Done means delivered messages with attachments no longer remain in the outbox or show a local failure notification, with regression coverage for that behavior.
