我想使用 Android 设备从我们自己的域(如 xyz@mycompany.com)发送电子邮件。
我们可以使用编写在 mainActivity 中的以下代码从 gamil 帐户发送邮件。
String managerUserName = "xyz@gmail.com";
System.out.println("Üser name = " + userName + " Password =="
+ password);
if ((userName != null && userName.length() != 0)
&& (password != null && password.length() != 0)
&& (managerUserName != null && managerUserName.length() != 0)) {
if (Util.isInternetOn(OrderActivity.this)) {
Mail m = new Mail(userName, password);
String[] toArr = { managerUserName };
m.setTo(toArr);
m.setFrom("wooo@wooo.com");
m.setSubject("MForce");
m.setBody("This mail is sended by Mforce application");
在 Mail.java 中，我们使用以下代码设置主机和端口
public Mail() {
_host = "smtp.gmail.com"; // default smtp server
_port = "465"; // default smtp port
_sport = "465"; // default socketfactory port
}
当我们尝试使用自己的域时，我们像这样更改了 Mail.java 中的主机名和端口号。
public Mail() {
_host = "smtp.myServerIp.com"; // default smtp server
_port = "25"; // default smtp port
_sport = "25"; // default socketfactory port
}
当我尝试使用我们的个人域从我的应用程序发送邮件时，使用 smtp，我在 logCat 中收到 javax.mail.messagingexception 无法连接到 smtp 主机异常，这是我的 logCat。

请一些人帮助我，在此先感谢。
最佳答案
有一个技巧。
在你的 mail.java 中必须有这段代码..
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.port", _port);
props.put("mail.smtp.socketFactory.fallback", "false");
此处开始两行不适用于不同的服务器，您需要对其进行注释 或者你可以这样做
if(_host.contains("gmail")||_host.contains("yahoo")){
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
}
props.put("mail.smtp.port", _port);
props.put("mail.smtp.socketFactory.fallback", "false");
现在看看魔术 :)
