The from address has changed since you started sending this

Error message

The from address has changed since you started sending this draft. Double-check the draft and click 'Send' again.

What it means

SendDraftTask.willBeQueued guard: the draft's from address no longer resolves to a configured account at queue time — the account was removed, or the draft's from header changed after sending began (e.g. default identity switched). The task refuses to send to prevent delivering mail from an address the user no longer controls.
