Connecting to the server from LAN

Table of Contents

If PostCast Server is installed on the computer that is connected to your LAN and if that computer has access to the Internet, then other computers on the network can use it as an SMTP mail server. Every computer on the network will be able to connect to PostCast Server and send messages to the Internet.

The program can also send messages to LAN addresses and mail servers that exist on your network. Every e-mail that is sent to LAN must be addressed using the following format: User@IP or User@Computer where 'IP' is the IP of the destination computer and 'Computer' is the name of that computer.

In order to successfully configure PostCast Server to accept connections from LAN, the local IP address or the name of the computer on which it is installed and under which other computers see it on the network should be entered in the "Host Name" settings. If you are not sure how those values are defined on the computer, select the "Show network configuration" option from the "Tools" menu.

The SMTP server address in the e-mail client should be the IP address or name of the computer with PostCast Server. Once you change the "Host Name" value in PostCast Server into the LAN IP address, you can no longer access it by using "localhost" (default value when connecting from the same computer). The LAN IP address should be entered in the e-mail client.

It is absolutely the same whether you use the computer name or IP address in server or client settings. In the situation below:

Computer name: Computer 1
Computer IP: 192.168.0.1

...the "Host Name" value in PostCast Server and the SMTP server address in the e-mail program that will connect to the server can be either '192.168.0.1' or 'Computer 1'.

Every computer on the network can send messages using the address or the name of the computer that has a copy of PostCast Server running. PostCast Server can sustain heavy loads and is able to process a number of requests at the same time. Up to 100 users who are sending messages can be connected to it at the same time. It represents an ideal solution both for small networks and for networks with a large number of connected computers.
