PostCast Server Version 2 descriptions PostCast Server is a free SMTP server program for Windows that enables you to send messages directly from your computer. This program is used for sending newsletters distributing messages to different mailing lists sending notifications to your customers as well as for sending individual messages. You can use it instead of the SMTP server of your Internet Service Provider . PostCast Server supports all e-mail programs. The program you already use for sending & receiving messages can be connected to the server in a very easy way - by altering just one parameter. Having done so you can send messages in a usual manner. Once the program has been set it performs all its tasks in the background. 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 & terminate the connection after completing its task. You can connect to it via LAN Internet or directly from the computer where it has been installed. The program can be configured to send messages for all users within LAN. If necessary it is possible to limit access to the program using several security options. It has been optimized for very fast message delivery & gets the most out of your Internet connection. While sending messages the program establishes dozens of connections at the same time. Thus it reaches maximum speeds & on average delivers about 3 500 messages per hour with an ordinary modem Internet connection & some 13 000 with an ISDN connection. The sending speed increases with the capacity of your Internet connection.
