* Speed up e-mail delivery by offloading the delivery task from your application. EasyMail SMTP Express is an e-mail queuing and delivery system. It intercepts messages from the EasyMail SMTP object, EasyMail .Net Edition SMTP class, EasyMail Advanced API SMTP library or other source and sorts, queues, and reliably delivers the messages in the background.
