因某部份互聯網服務供應商(ISP)封鎖了埠(Port)25, 禁止客戶使用對外的SMTP 25 Port.
客戶可以使互聯網服務供應商提供的SMTP外, 我們還提供了SMTP 1025 Port 服務.
Since a part of the Internet Service Provider (ISP) blocked the Port 25, it prohibited users to use the external SMTP Port 25.
Except ISP offers SMTP service, we also provide SMTP Port 1025 services.
