SmtpServer is a powerful Smtp Server and it will allow you use your computer to send e-mails directly to recipients bypass your ISP's mail server, and sender will get a notification email when the email is opened. Along with a subscription-based mass mailer the program can be used as a relay server for sending requested newsletters, distributing messages to different mailing lists, sending notifications to your customers, as well as for sending personalized messages.

You can use it instead of your ISP's SMTP server to increase your security an privacy. SmtpServer supports all email programs like Outlook Express, Eudora, IncrediMail, the Bat!, Mutt, KMail, Pegasus, DevMail, Mail Bomber, Delta Mail, Foxmail, and more! The email program you already use for sending and receiving messages can be connected to the server in a very easy way - just by using local machine IP (for example127.0.0.1) instead of your current Outgoing email (SMTP). Having done so, you can send messages in a usual manner.
