The Problem
I’m using Mailspring with multiple connected accounts.
Frustratingly, I am often sending mails from the wrong mail account as I forget to change the sender to the proper mail account. Only later I see that the mail was sent from the wrong account.
Proposed Solution
Instead of simply selecting the top most account as default, I’d appreciate a setting to the Composing section to have the From: field be unset when composing new mails.
This way I would need to actively select a mail account from the drop-down before being able to send a message. When trying to send a mail without selecting a from mail account first, it should result in a message similar to the current message when leaving the recipients field empty:
Cannot send message
You need to select a sender account before sending the message.
I think this should be quite easy to implement. I would also be open to add a PR myself if you would be open to merge and release it.
