WHMCS is a very powerful financial management system. Since I used WHMCS to connect SolusVM when building its cloud host, I found that I encountered many problems when using WHMCS. The first problem is that WHMCS switches to SMTP for sending letters. By default, you can use PHP of WHMCS to send letters, but most of the letters sent are thrown into the trash by major mail providers.
Recently, "coveting" a bargain, I changed the server to Alibaba Cloud International Edition Hong Kong VPS host. The biggest feeling after moving here is not the speed improvement - because the Korean kdatacenter VPS originally used is also very fast when accessed on the telecommunications network - but the performance of the Alibaba Cloud VPS host is really good compared to other VPS hosts that are also 1GB.

When many people think of statistics, they are limited to Google Analytics, Baidu Statistics, webmaster statistics, etc. These types of statistics are systems developed by third-party companies such as search engines. Naturally, they are useless in terms of functionality and ease of use, but the only One problem is that statistical data is stored on a third-party server, which poses certain risks for some websites with strong confidentiality.
RaySync is a very large file transfer acceleration service developed by Shenzhen Yunyu Technology. It is designed to provide big data transfer services for large and medium-sized companies such as Huawei. RaySync's TCP-based transmission is reliable.
