无法在Google App Engine上发送电子邮件

陈冠希：

我尝试使用Javamail发送电子邮件。但是，我收到以下消息：

javax.mail.SendFailedException: Send failure (javax.mail.MessagingException: Illegal Arguments (java.lang.IllegalArgumentException: Bad Request: ))

我试图从管理员帐户（用于上传应用程序）以及我登录到该应用程序的用户帐户发送电子邮件。（来自UserService - getCurrentUser().getEmail()）都失败了。

我想知道是否需要设置任何特殊设置？

    Properties props = new Properties();
    Session session = Session.getDefaultInstance(props, null);    
    Message msg = new MimeMessage(session);
    UserService userService = UserServiceFactory.getUserService();
    String email = userService.getCurrentUser().getEmail();
    //Or
    //String email = "[email protected]";
    msg.setFrom(new InternetAddress(email));
    msg.addRecipient(Message.RecipientType.TO,
                     new InternetAddress("[email protected]"));
    msg.setSubject("Test Email");
    msg.setText("Nobody");
    Transport.send(msg);

视力：

真的很奇怪。我只写了以下示例：

UserService userService = UserServiceFactory.getUserService();
String thisURL = request.getRequestURI();
if (request.getUserPrincipal() != null) {
    response.getWriter().println("<p>Hello, " +
                                request.getUserPrincipal().getName() +
                                "!  You can <a href=\"" +
                                userService.createLogoutURL(thisURL) +
                                "\">sign out</a>.</p>");
    Properties props = new Properties();
    Session mailSession = Session.getDefaultInstance(props, null);    
    Message msg = new MimeMessage(mailSession);
    String email = userService.getCurrentUser().getEmail();
    //Or
    //String email = "[email protected]";
    msg.setFrom(new InternetAddress(email));
    msg.addRecipient(Message.RecipientType.TO,
                     new InternetAddress("[email protected]"));
    msg.setSubject("Test Email");
    msg.setText("Nobody");
    Transport.send(msg);
    response.getWriter().println("<p>Sent email!</p>");
} else {
    response.getWriter().println("<p>Please <a href=\"" +
                                userService.createLoginURL(thisURL) +
                                "\">sign in</a>.</p>");
}

没有例外，我确实收到了电子邮件。您确定实际应用中没有更多操作吗？
