Complete Mail Server

If you're looking for a reliable mail server software that's both flexible and fast, Complete Mail Server might be just what you need. It's designed specifically for corporations and ISPs, and comes with a range of advanced features and security options. One unique benefit is that it can be installed on multiple computers for parallel mail processing, with the common message queue and mailboxes kept on separate dedicated computers.

It's also very user-friendly, with a separate interface that you can install on your PC to manage all your server installations from one place. The SMTP and POP3 services can be set up as NT services, so they'll keep working even when you're logged off. There's even a special test mode for debugging and testing purposes, which allows developers to check if their scripts work properly.

Another useful feature is the SMTP Gateway Servers, which makes Complete Mail Server ideal for personal use too. If you travel around the world and need to switch ISPs frequently, simply add all your SMTP servers to the list of gateway servers. The program will automatically find the correct SMTP server, so you won't have to modify your email program's settings every time you switch ISPs.

Overall, if you're after a high-performance mail server that's both flexible and convenient, Complete Mail Server is definitely worth considering.
