Thunderbird 客户端拷贝到发送文件夹失败

note thunderbird

For you xtu mail account, a copy of the sent message is automatically stored in the IMAP Sent folder, so you should uncheck "Place a copy in" under Tools/Account Settings/accountname/Copies & Folders.

邮件服务器已经把发送的邮件保存到 sent 文件夹了，因此在 thunderbird 客户端的账户设置中的 Copies & Folders 页面下， Uncheck “Place a copy in” 即可。
