PostCast Server is an SMTP server that enables you to send messages directly from your computer. It is used for sending newsletters, distributing messages to different mailing lists, sending notifications to your customers, as well as for sending individual messages. The program you already use for sending and receiving messages can be connected to the server. Having done so, you can send messages in a usual manner. You can set the program to send messages on a daily basis, every hour, immediately after downloading them, or in some other time interval. If necessary, the program will automatically call your ISP and terminate the connection after completing its task.
