阿里云服务器发送邮件失败，25端口被禁用，采用ssl 方式 465端口发送

本地发送邮件没问题，部署在阿里云上邮件发送不出去，搜集整理后发现是阿里云禁用25端口导致。解决方法如下：

public static boolean sslSend(String content)
        throws AddressException, MessagingException, IOException{

 MessageInfo msg1 = new MessageInfo();
    msg1.setFrom("发件人邮箱");
    msg1.setSendDate(new Date());
    List list = new ArrayList<>();
    list.add("收件人邮箱");
    msg1.setTo(list);
    msg1.setMsg("内容");
    msg1.setSubject("主题");

    EmailAccount emailAccount = new EmailAccount();
    emailAccount.setUsername("邮箱名");
    emailAccount.setPassword("密码");
    emailAccount.setPlace("邮箱服务器");

    Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
    final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
    // Get a Properties object
    Properties props = new Properties();
    props.setProperty("mail.smtp.host", emailAccount.getPlace());
    props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
    props.setProperty("mail.smtp.socketFactory.fallback", "false");
    props.setProperty("mail.smtp.port", "465");
    props.setProperty("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.auth", "true");

    final String username = emailAccount.getUsername();
    final String password = emailAccount.getPassword();
    Session session = Session.getDefaultInstance(props, new Authenticator(){
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }});
    Message msg = new MimeMessage(session);

    // 设置发件人和收件人
    msg.setFrom(new InternetAddress(emailAccount.getUsername()));
    List tos = msg1.getTo();
    Address to[] = new InternetAddress[tos.size()];
    for(int i=0;inew InternetAddress(tos.get(i));
    }
    // 多个收件人地址
    msg.setRecipients(Message.RecipientType.TO, to);
    msg.setSubject(msg1.getSubject()); // 标题
    msg.setText(msg1.getMsg());// 内容
    msg.setSentDate(new Date());
    Transport.send(msg);
    System.out.println("EmailUtil ssl协议邮件发送打印" +msg.toString());
    return true;
}

static class EmailAccount{
    // 邮箱用户
    private String username;

    // 邮箱密码
    private String password;

    // 邮箱服务器
    private String place;

    public String getUsername() {
        return username;
    }

}

static class MessageInfo{
    private String  from;

    private List to;

    private Date sendDate;

    private String subject;

    private String msg;

    public String getFrom() {
        return from;
 }

}
