从上面的文字中，我无法找到错误原因。
注意：它适用于许多发件人。我没有为邮件服务启用登录：管理员。
这是我的代码片段：
应用程序.yaml

process_email.py 中的处理程序
def receive(self, mail_message):
if not hasattr(mail_message, 'attachments'):
err = 'No attachment found.'
self.status = 'ERROR'
self.status_message.append(err)
self.SendStatusMail(mail_message.sender)
return
for name, content in mail_message.attachments:
report_time_period = self.GetReportTimePeriod(name)
report_date = self.GetReportDate(name)
if report_time_period and report_date and name.endswith('.csv'):
records, product_prefix = self.ProcessCsv(content)
if records and product_prefix:
self.UpdateRecordsToDb(report_time_period, report_date, records,
product_prefix)
else:
err = ('Invalid file name %s.' % (name))
self.status = 'ERROR'
self.status_message.append(err)
self.SendStatusMail(mail_message.sender)
有什么建议可以找到反弹的原因吗？
