如何查询企业邮箱的服务地址？

1...引入依赖

    <!-- 4.引入email API--> 
       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>    

2...配置

spring:
  application:
    name: test-config-server
  profiles:
  mail:
    host: smtp.163.com #发送邮件服务器
    username: ppyun7c@163.com #163邮箱
    password: wdsqm01 #客户端授权码
    protocol: smtp #发送邮件协议
    properties.mail.smtp.auth: true
    properties.mail.smtp.port: 465 #端口号465或994
    properties.mail.display.sendmail: XIEDONGXU #可以任意
    properties.mail.display.sendname: Spring Boot Guide Email #可以任意
    properties.mail.smtp.starttls.enable: true
    properties.mail.smtp.starttls.required: true
    properties.mail.smtp.ssl.enable: true
    default-encoding: utf-8
    from: ppyun7c@163.com #与上面的username保持一致

3...代码

package com.test.domi.service;

import javax.mail.MessagingException;

public interface IMailService {
    /**
     * 发送文本邮件
     * @param to
     * @param subject
     * @param content
     */
    public void sendSimpleMail(String to, String subject, String content, String... cc);

    /**
     * 发送HTML邮件
     * @param to
     * @param subject
     * @param content
     * @throws MessagingException
     */
    public void sendHtmlMail(String to, String subject, String content, String... cc)throws MessagingException;

    /**
     * 发送带附件的邮件
     * @param to
     * @param subject
     * @param content
     * @param filePath
     * @throws MessagingException
     */
    public void sendAttachmentsMail(String to, String subject, String content, String filePath, String... cc)throws MessagingException;

    /**
     * 发送正文中有静态资源的邮件
     * @param to
     * @param subject
     * @param content
     * @param rscPath
     * @param rscId
     * @throws MessagingException
     */
    public void sendResourceMail(String to, String subject, String content, String rscPath, String rscId, String... cc)throws MessagingException;

}

4...实现类

        message.setCc(cc);
        message.setSubject(subject);
        message.setText(content);
        mailSender.send(message);
    }

    /**
     * 发送HTML邮件
     * @param to

        helper.setCc(cc);
        helper.setSubject(subject);
        helper.setText(content, true);
        mailSender.send(message);
    }


    /**

        FileSystemResource file = new FileSystemResource(new File(filePath));
        String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
        helper.addAttachment(fileName, file);
        mailSender.send(message);
    }

    /**
