When setting up a mail server, one of the most frustrating issues users face is that port 25 is often blocked. This port is essential for SMTP services. Most cloud hosting providers disable port 25 by default due to anti-abuse concerns. The good news is that Wanwei Telecom has launched a Hong Kong cloud server specifically designed for email use, with port 25 enabled by default. It also supports multiple Linux distributions and Windows systems, providing a very friendly environment for building mail server systems.
