我已经使用 app 编写了一个 gae 引擎 java mail api。
我的 appengine-web.xml：
<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
<application>mailapps</application>
<version>1</version>
<!--
Allows App Engine to send multiple requests to one instance in parallel:
-->
<threadsafe>true</threadsafe>
<!-- Configure java.util.logging -->
<system-properties>
<property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
</system-properties>
<!--
HTTP Sessions are disabled by default. To enable HTTP sessions specify:
<sessions-enabled>true</sessions-enabled>
It's possible to reduce request latency by configuring your application to
asynchronously write HTTP session data to the datastore:
<async-session-persistence enabled="true" />
With this feature enabled, there is a very small chance your app will see
stale session data. For details, see
http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling_Sessions
-->
</appengine-web-app>
当我在 localhost 上运行该应用程序时，我一切正常，但是当我在 gae 上运行部署它并运行它时，我得到：
错误：服务器错误 服务器遇到错误，无法完成您的请求。
如果问题仍然存在，请报告您的问题并提及此错误消息和导致它的查询。
我的应用程序有什么问题？你能帮我么？

盖伊日志说：
java.lang.RuntimeException：javax.mail.SendFailedException：发送失败（javax.mail.MessagingException：非法参数（java.lang.IllegalArgumentException：未经授权的发件人：未经授权的发件人））
