EGO is a portable email server for everybody, click-to-go, reliable and safe. The unique thing about EGO is that it links the email application and recipient's mail server together - this means that the email application and recipient's mail server talk directly - at just the same second as the application finishes sending the message, the message is in the recipient's incoming mailbox.

EGO has the following features:

1. Works seamlessly and directly between your email application and the receiver's mail server. Unlike other SMTP servers, which buffer the mails and send them later, eGo acts as a go-between for the mail application and the recipient's mail server - the receiving and sending occurs simutaneously - so you can know the sending result from your email application: If the mail application says OK, the message have already reached the receiver's mail server, waiting the recipient to check; if it says something wrong, you know it immediatly - you wont get a "Undelivered Message Notice" hours later.

2. Reliable security. By default, eGo only accepts connections from the computer on which it is running. If you allow other computers to share eGo's service, you must add that computer's IP address explicitly.

3. Start and Exit quickly. It is a user mode application, not a system service. You can start it and quit it as you do with any other user mode applications, such as your email application or word processer.

4. Efficient and Easy to Use. It is a Win32 application. The executable file size is only about 105K. The user interface have only four buttons and a window display server and client status.
