Mail Server Pro is a high-performance SMTP/POP3 server program that can be used by corporations and Internet Service Providers where having an ultra fast and reliable mail server is a necessity. It can be used along with virtually any mailer or email program including Microsoft Outlook, Outlook Express, Eudora, Netscape and The Bat. Although, Mail Server Pro is simple from the first look, it hides a real power. It is absolutely bullet-proof, it has a lot of security features and options that allow you to protect the server from DDoS attacks as well as safely block SPAM and spammers. Another great feature is that Mail Server Pro can be installed on several computers while the common message queue and user mailboxes can be kept on separate dedicated PCs. This will definitely facilitate email messaging in your organization. The user interface of the program is flexible and very easy to learn. You can install the SMTP/POP3 services of Mail Server Pro on several computers and configure all of them from a single PC where you can install the user interface of Mail Server Pro only. The SMTP and POP3 services work as NT services therefore they will keep working in the logoff mode. For software debugging and testing purposes, the program has a testing mode you can use to check if your email clients work correctly. After you enable the testing mode, the server will accept your email messages, store them in the queue but will not deliver them to the actual recipients. As a personal solution, it is ideal for laptop PC users who travel a lot and have to use different Internet Service Providers (ISP) on the run. Using Mail Server Pro, you will never encounter a sending problem wherever you connect your PC to a network or phone socket. If the program can not deliver your email message directly, it will try to deliver it through SMTP gateway servers. You can maintain an unlimited number of SMTP gateway servers to achieve the best delivery rate. Just add all your SMTP servers you use in different places to the list of gateway servers and the program will always use a correct SMTP server wherever you connect your PC to the Internet; you do not have to modify SMTP settings of your email program each time you change ISPs anymore. The user interface of the program is very easy to learn, excellent documentation is included. ...
