邮件转发问题整理

1.阿里云禁用25端口解决方案修改为465端口

spring:
  mail:
    host: smtp.163.com
    username: xx@163.com
    password: 授权码
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
            required: true
          socketFactory:
            port: 465
            class: javax.net.ssl.SSLSocketFactory
            fallback: false

2.文件名超长

System.getProperties().setProperty("mail.mime.splitlongparameters", "false");

#文件名编码修改
MimeUtility.encodeWord(file.getName())
