App

None

Device model

Motorola Edge (2022)

Steps to reproduce

This is the second time that I've noticed this error and I realize now why it's happening. When I've changed the from email address to one other than the main email address, it tries to send the email from the main email outbox, instead of the Outbox for the other email account that I changed the from email to.

1. Add two or more email accounts to K-9-Mail.
2. Start writing an email to someone from an email link on a website.
3. Change your from email address to another other than the default email address.
4. When you try to send it, the error will appear in the notifications and the email will stay in the Outbox for the wrong email account.

Expected behavior

The email should be placed in the Outbox for the email address that the from email address was changed to.

Actual behavior

The email stays in the wrong outbox and the error comes up again every time it checks for new mail and/or sending mail.

Thank you, Shalom.

Start by reproducing the two-account workflow described in the issue and read the attached logs, focusing on the MessagingController: Skipping sending message entry. Trace the send and outbox selection path for a changed From address. Done means the message is placed in the selected account's Outbox and sends without the 5.1.3 mismatch error.
