The Simple Mail Transfer Protocol (SMTP) carries the electronic mail of the world. This solution provided by RapidCompute, is completely independent of the user’s email client and sends email directly to or from an SMTP Server.

Without it, your emails would go nowhere.

Availing this service means that in a multi-user environment, you only have to setup your email settings once on the server, and then no matter how many changes there are to the window’s versions or the workstation’s email clients, your application keeps working.
