Google App Engine（Python） - 邮件已发送但未收到 [英] Google App Engine (Python) - Mail sent but not received

问题描述

下面是我用来发送邮件的代码（不完全一样，我有一个不同的主体和发件人的邮件，我没有因为隐私原因而提出）：

  body =Some body
 subject =Some Subject
 email = user.email＃user.email返回一个有效的电子邮件地址
 
 mail.send_mail（'[e-mail]'，email，subject，body）
  

这些代码在没有Exception的情况下执行，我的App Engine配额对Mail API的调用增加，发送的电子邮件数量的配额也增加，表示发送成功的电子邮件。但是，当我检查我的邮件时，我没有收到邮件。

我尝试更改主题，正文，发件人电子邮件等，但我是否收到邮件似乎完全是随机的 - 我有时（很少）收到邮件，而在其他时间收到邮件。这些邮件甚至不在我的垃圾邮件文件夹中。

发生了什么事？我该如何确保每次收到邮件？ 解决方案

对于第二个问题：无法确保邮件（没有额外的额外收据确认服务 - 一个不同的野兽），你最多可以检测它们是否顺利通过邮件发送基础设施。另请参阅 web2py中的mail.send（）功能用于不存在的退回的电子邮件/电子邮件地址。

Here's the code I'm using to send mail (not exactly, I have a different body, subject and the sender's mail that I haven't put up for privacy reasons):

body="Some body"
subject="Some Subject"
email = user.email # user.email returns a valid email address

mail.send_mail('[e-mail]', email, subject, body)

The code executes without Exception, my App Engine Quota for calls to the Mail API increases, as does the quota for the number of emails sent, indicating a successful email send. However, when I check my mail, I do not get the email.

I've tried changing the subject, body, sender email etc. but whether or not I receive the mail seems totally random - I receive it sometimes (rarely) and don't at other times. The mails aren't even there in my spam folder.

What's going on? And how do I ensure that the mail is received each time?

解决方案

For the 2nd question: you can't ensure the messages are received (without an additional extra receipt acknowledging service - a different beast), you can, at best, detect if they are passed successfully to the mail sending infrastructure or not. See also mail.send() feature in web2py for bounced email/ email address that doesnt exist.
