Mail Direct is a software that will allow you bypass your ISPs mail server and use your computer to send e-mails directly to recipients. It uses a built-in SMTP server which you can use instead of your ISPs mail server. All you have to do is set up your Email client to use "localhost" as your outgoing mail server and run Mail Direct. The software will then deliver any Email that you send out through it, and it will terminate delivery of messages that you have sent out to wrong or bad Email addresses. Mail Direct also comes with a failover option, that can automatically sent failed mail to a different SMTP server.

The license of this software is Free Trial Software, the price is $20.00, you can free download and get a free trial.
