Dear Valued Customer,
Starting from December 1, 2025, all servers in Hong Kong, Japan, and Singapore will implement a default block on Port 25 (SMTP).
This action is taken to prevent abuse and enhance system security.
If you require continued access to Port 25 for email services, please submit a support ticket to request activation, ensuring uninterrupted service.
Important Notice:
CTGServer strictly enforces a zero-tolerance policy for spam. Any form of spam activity will be considered a severe violation, and services will be immediately suspended upon detection.
Thank you for your understanding and support. We are committed to providing you with efficient and secure network services.
