I don't know if it is what is throwing you off... but sender should be like this:

<pre><code>sender = '&lt;admin_address@gmail.com&gt;',
</code></pre>

you are missing the '&lt;' for the sender. Sometimes it throws an error downstream of where the actual error is.

Also, make sure the admin_address@gmail.com is a Google Account that has been added as a developer for that app.

++)|1409200|如果您只想发送给管理员，则使用以下命令：|1409201|mail.send_mail_to_admins(sender='admin@yourdomain.com',++++++++++++++++++++++++++++++++subject=request.POST.get('email_title'),++++++++++++++++++++++++++++++++body=request.POST.get('email_body'),++++++++++++++++++++++++++++++++html=request.POST.get('email_body'))|offset|length|style|CODE|1409202|entityMap^0|0|0|0|0|0|0|7B|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|Y|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|Z|8|@$O|10|P|11|Q|R]]|9|@]|A|$]]|$1|S|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|T|$]]

Try this:

<pre><code>def email_member(request):
 to_addr = request.POST.get('email_to')

 if not mail.is_email_valid(to_addr):
 # Return an error message...
 pass
 else:
 # note we can also send html email, e.g. html='&lt;html&gt;&lt;head&gt;&lt;/head&gt;&lt;body&gt;Hello world&lt;/body&gt;&lt;html&gt;'
 mail.send_mail(
 sender='admin@yourdomain.com',
 to=to_addr,
 subject=request.POST.get('email_title'),
 body=request.POST.get('email_body'))
</code></pre>

I suggest you also send your email within the taskqueue, so you could setup something like this, you could pass over a unique parameter so that you are less likely to be hacked.

<pre><code>def mail_member_information(email_to, email_title, email_body):
 taskqueue.add(
 url = 'email_message',
 params =
 {
 'email_to': email_to,
 'email_title': email_title,
 'email_body': email_body,
 'valid_guid': 'ae9e34ca-a2c5-476e-b8be-72d807e3dc6b'
 }
 )
</code></pre>

If you just want to send to the administrators then use this:

<code>mail.send_mail_to_admins(sender='admin@yourdomain.com',
 subject=request.POST.get('email_title'),
 body=request.POST.get('email_body'),
 html=request.POST.get('email_body'))</code>

blocks|key|1509226|text|我认为你可以这样发送，确保发送者是应用程序的管理员|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1509227|from+google.appengine.api+import+mail

I think you can send like this, make sure that sender is a admin of the app

<pre><code>from google.appengine.api import mail
mail.send_mail(sender="something@gmail.com",

 to=email_valid.email,
 subject="Please validate your email",
 body=body_text,
 html=htmlbody_text)
</code></pre>

I'm trying to send an email from within Google App Engine.

Whenever I try to send, I get a "Missing subject error".

When I run the code on the development server, it seems to work fine - the console output looks right and I'm taken to the page that I was expecting. But when I upload it and run it, I get:

<pre><code>Traceback (most recent call last):
 File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/__init__.py", line 636, in __call__
 handler.post(*groups)
 File "/base/data/home/apps/spam-tool/1.349401522260793315/spam-tool.py", line 34, in post
 body=cgi.escape(self.request.get('content')))
 File "/base/python_runtime/python_lib/versions/1/google/appengine/api/mail.py", line 297, in send_mail
 message.send(make_sync_call)
 File "/base/python_runtime/python_lib/versions/1/google/appengine/api/mail.py", line 799, in send
 raise ERROR_MAP[e.application_error](e.error_detail)
BadRequestError: Missing subject
</code></pre>

But there's definitely a subject.

The code I'm using is:

<pre><code>&gt; message = mail.EmailMessage(sender="admin_address@gmail.com&gt;",
 subject="test")
 message.subject=self.request.get('content')
 message.to = addr_to_send_to
 message.body = self.request.get('content')
 message.send()
</code></pre>

(Yes, the subject is set twice... I've tried only setting it in one place or the other, and neither worked.)

Thanks in advance.
