伊马利布。IMAP4.error：命令 SEARCH 在 AUTH 状态中是非法的，只有在 SELECTED 状态中才允许，即使我应该不在 auth 状态中

问：

我收到此错误，我不知道为什么，这是方法：

def recieve(self, host: str, port: int, user: str, password: str, mailbox: str, batch_size: int = 0, logout_after: bool = True):
        """
        mailbox gotten from mailboxes() method.
        a batch size of 0 means all emails, batch sizes get most recent amount of emails in mailbox.
        """
        try:
            with imaplib.IMAP4_SSL(host, port) as imap:
                
                imap.login(user=user, password=password)
                imap.select(mailbox)
                rv, data = imap.search(None, "ALL")
                
                if batch_size == 0:
                    for num in data[0].split():
                        rv, data = imap.fetch(num, '(RFC822)')
                        print(data)
                        if rv != 'OK':
                            print ("ERROR getting message", num)
                            return
                else:
                    for num in data[0].split()[-batch_size:]:
                        rv, data = imap.fetch(num, '(RFC822)')
                        print(data)
                        if rv != 'OK':
                            print ("ERROR getting message", num)
                            return
                    
                imap.close()
                
                if logout_after:
                    imap.logout()

        except Exception as e:
            raise e

我按这个顺序使用 imap.login，然后是 imap.select，最后是 imap.search，所以我应该离开身份验证状态并进入选定状态，我是否遗漏了什么？
