我正在尝试使用我的 gmail 地址发送和发送电子邮件。我将调试设置为 true，这就是我得到的。

然后我什么都不做，没有错误/警告/....
我正在使用这些设置：
mail.smtp.auth=true
mail.debug=true
mail.smtp.host=smtp.gmail.com
mail.smtp.user=MyOwnUserName@gmail.com
mail.smtp.password=MyOwnPassword
mail.transport.protocol=smtp
mail.smtp.port=465
mail.disable=false
mail.verbose=true
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
我试过这些例子：
都是一样的问题。而且我 100% 确定我的密码和电子邮件地址是正确的。
编辑：我的代码（与第一个链接相同） nitialContext ic = new InitialContext(); 会话会话 = (会话) ic.lookup("mail/SugarCRMMailSession");
Properties props = session.getProperties();
String to = emailID;
String mailhost = props.getProperty("mail.smtp.host");
String user = props.getProperty("mail.smtp.user");
String password = props.getProperty("mail.smtp.password");
String protocol = props.getProperty("mail.transport.protocol");
String authorization = props.getProperty("mail.smtp.auth");
String mailDisabled = props.getProperty("mail.disable");
String verboseProp = props.getProperty("mail.verbose");
String debugProp = props.getProperty("mail.debug");
boolean sentDisabled = false;
if(mailDisabled.equals("true"))
sentDisabled = true;
if(!sentDisabled){
boolean auth = false;
if(authorization.equals("true"))
auth = true;
boolean verbose = false;
if(verboseProp.equals("true"))
verbose = true;
String mailer = "smtpsend";
if(debugProp.equals("true"))
session.setDebug(true);
else
session.setDebug(false);
Message msg = new MimeMessage(session);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to, false));
msg.setSubject(subject);
msg.setContent(text, "text/html;charset=UTF-8");
msg.setHeader("X-Mailer", mailer);
msg.setSentDate(new Date());
SMTPTransport t = (SMTPTransport)session.getTransport(protocol);
try {
t.connect(mailhost, user, password);
t.sendMessage(msg, msg.getAllRecipients());
} finally {
t.close();
}
System.out.println("\nMail was sent successfully.");
}else{
System.out.println("Mail Sending is disabled.");
