Research direction
Reproduce the issue in Thunderbird for Android 20.0 with a 163 Mailbox sender on Android 16, then compare the Sent folder with the 163 Mailbox website. Trace the sending and Sent-folder synchronization flow to identify why both copies appear. Done means a sent message appears only once while preserving the provider's send-status behavior.
