我无法从Sent文件夹中删除电子邮件。它可以很好地从Inbox文件夹中删除。我尝试使用Sent和[Gmail]/Sent参数，但都不起作用。问题出在哪里？
import imaplib
email = "my@gmail.com"
passw = "mypass"
imapserver = "imap.gmail.com"
def deleteEmailIMAP(user, password, IMAP):
mail = imaplib.IMAP4_SSL(IMAP)
mail.login(user, password)
mail.select("[Gmail]/Sent")
typ, data = mail.search(None, 'subject 2f0802e2-e396-4a37-aeae-3a51b6ad288f')
for num in data[0].split():
mail.store(num, '+FLAGS', r'(Deleted)')
mail.expunge()
mail.close()
mail.logout()
deleteEmailIMAP(email, passw, imapserver)

该代码不处理错误。这就是为什么它不会捕获服务器对SELECT命令的标记NO响应。它在错误日志中也不可见，但您报告的异常意味着，当代码发出SEARCH时，没有打开任何邮箱，这意味着SELECT一定失败了。(检查IMAP协议状态。(
GMail使用本地化的邮箱名称，因此可能的罪魁祸首是您身份验证的用户没有名为[Gmail]/Sent的邮箱。如果您需要发现"；已发送文件夹"；邮箱名称，请尝试RFC 6154(或参阅谷歌的文档(。
