As you may know, PSPINC provides web and email hosting services, primarily targeting small- and medium-sized businesses in the U.S. and Japan. However, our email hosting service isn’t just a third-party mail server solution.

PSPINC’s mail server is a second-generation system we developed in-house. We built the first-generation mail server on a Windows-based system operated on Windows servers. Later, we transitioned all our mail servers to a Linux-based platform, which evolved into our current advanced mail server. This proprietary mail server is now the foundation of PSPINC’s email hosting service today.

Migration in Japan

In Japan, we’re migrating our mail server from the first generation to the second generation. We expect this transaction will significantly improve our server’s overall security and processing speed. Since PSPINC’s mail servers manage many domains in Japan, upgrading to the latest environment requires some time. However, we’re ensuring a smooth backend migration to minimize any impact on our customers.

The Strengths of PSPINC’s Mail Server

PSPINC’s mail server comes equipped with the following standard features:
●    Virus scanning
●    Malware detection
●    Phishing protection
●    Spam filtering
●    Auto-reply functions
●    Mail forwarding capabilities
●    Automatic archiving

Integrating these features directly into the mail server results in highly efficient processing.  Additionally, since we’ve developed our system in-house, we maintain full control at the source-code level, making it easy to respond quickly to new security threats.

The first mail server PSPINC developed was a Windows-based mail server (ST Mail). However, our current mail server (ML Server), which runs on Linux, operates using the latest OS environment, which provides a more stable performance. 

Differences from Other Services

Unlike other email hosting services that rely on third-party mail servers, PSPINC’s solution is fully developed in-house. As a result, we offer higher processing power, a more stable operation, and a reliable environment with minimal downtime compared to other providers.

If you’re looking for a dependable business email server, we encourage you to consider PSPINC’s email hosting service. It’s also available in Japan, and we can implement our email server through authorized resellers. Please feel free to contact us for more information.
