Firewall configuration user password mailbox random send

Not involved, firewall can access the public network

The firewall configures local users, and the user password is sent to the user randomly via mailbox. A prompt indicates Operation fail, please check mail server configuration

Configure mail server

The site uses qq mailbox. By capturing the corresponding packets, it was found that after the configuration is completed, the firewall will attempt to log in to the server using the subscriber provisioning login information. The qq mailbox prompts 530 fail, and the reason for the failure is the lack of ssl encryption

Acknowledge that the firewall currently does not support the SSL encryption function for login. Since QQ mailbox does not support disabling this verification, it is necessary to switch to another mail server without SSL encryption requirements.
