电子邮件配置正确，但无法发送 The email configuration is correct, but it cannot be sent

[TC-THREE]

邮件服务器用的是docker-mailserver，没有配置过什么东西，仅仅创建了一个邮件账户，使用roundcube可以正常收发邮件，但是cloudware发送不了，无论是否打开强制使用ssl，图片第一个是强制ssl的报错，第二个是关闭强制ssl的报错

The email server uses Docker MailServer and has not been configured with anything. Only one email account has been created, and using RoundCube can send and receive emails normally. However, Cloudware cannot send emails, regardless of whether SSL is enabled or not. The first line shows an error message for forcing SSL, and the second line shows an error message for disabling SSL

这种要么发件那边不兼容要么就是你配置错了
