STARTTLS is required but host does not support STARTTLS

Spring boot 邮件系统的错误,需要修改配置的文件yml.如果是企业邮箱的话就需要进行这个配置:

spring:
  mail:
      host: mail.ccds.com
      username: [e-mail]
      password: 123456
      protocol: smtp
      default-encoding: UTF-8
      properties:
        mail.smtp.socketFactory.fallback: true
        mail.smtp.starttls.enable: false
        mail.smtp.starttls.required: false
        mail.smtp.starttls.auth: true

重点是:

     mail.smtp.starttls.enable: false
     mail.smtp.starttls.required: false
设置为false.
配置为properties.yml
