HDC调试需求开发（15万预算）,能者速来！>>>
最近在做一个项目用到javamail推送邮件，我在本地项目(WIN10系统)里配置好之后是可以成功发送邮件的，但是放到服务器（WIN SERVER 2012 R2）上就有一些问题，没有报错，也catch不到异常，但是填写的邮箱接收不到邮件。这里是代码。找不到是什么原因，寻求帮助。

final String to = "我自己的邮箱";
final String from = "我自己的邮箱";
final String host = "邮箱服务器";
final Properties properties = System.getProperties();
properties.setProperty("mail.smtp.host", host);
properties.setProperty("mail.smtp.auth", "true");
properties.setProperty("mail.smtp.port", "587");
final Session session = Session.getDefaultInstance(properties, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("我的邮箱", "我的邮箱密码");
}
});
try {
String nick = "";
try {
nick = MimeUtility.encodeText("管理员");
} catch (Exception e) {
e.printStackTrace();
}
final MimeMessage message = new MimeMessage(session);
message.setFrom((Address) new InternetAddress(String.valueOf(nick)
+ " <" + from + ">"));
message.addRecipient(Message.RecipientType.TO,
(Address) new InternetAddress(to));
message.setSubject("新留言");
message.setContent(
(Object) ("<h1>你好</h1>"),
"text/html;charset=gb2312");
Transport.send((Message) message);
System.out.println("发送成功");
} catch (MessagingException mex) {
System.out.println("发送失败");
mex.printStackTrace();
}
