从上面的文字，我无法找到错误原因。

注意：它适用于许多发件人。我没有启用login：admin for mail service。

这是我的代码段：

的app.yaml

--------

application: my-app
version: 2
runtime: python
api_version: 1

handlers:
- url: /remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin

- url: /_ah/mail/sometext@my-app.appspotmail.com
  script: process_email.py

- url: .*
  script: main.py

inbound_services:
- mail

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)

有任何建议可以找到反弹的原因吗？

Answer 1

将代码放在try-catch中并在处理附件时遇到错误： '在不带引号的字段中看到的新行字符 - 您是否需要以通用换行模式打开文件？'它已使用content.decode（）。splitlines（）解析。

虽然邮件仍然到达目的地，但它不应该给邮件传递失败。谢谢JoSo。
