SMTP Relay Server is a SMTP server program for Windows that lets you convert any Windows based PC into SMTP server. You are allowed to use it either on a dedicated server or on a personal computer in the background. It can be used along with any mailer or email program working on the same computer or on a separate computer connecting to SMTP Relay Server using TCP/IP protocol. Traveling laptop PC users using different Internet Service Providers (ISP) on the go may use SMTP Relay Server as a gateway SMTP server that either sends your messages directly when possible or redirects them to other SMTP accounts if direct sending is blocked by the current ISP.

The email program you already use for sending and receiving messages can easily be used along with the server just by using the IP address "127.0.0.1" instead of your current SMTP host. SMTP Relay Server offers you a lot of security options to protect your machine from hacker attacks and filter SPAM.
