1. What does the message "Smtp Server can't run - Can't bind socket" mean?

Default port for receiving connection is 25 TCP. This message means that this port is already in use by another application. If you work under Windows 2000, the port might be in use by the "Simple Mail Transfer Protocol" service. This service is not an important component of the operation system, unlike, for example TCP/IP. Therefore you can disable it. To do that, open the "Control Panel" \ "Administrative Tools" \ "Services" window and change "Simple Mail Transfer Protocol" service startup type to manual and then stop the service.

To find out what application is using port 25, you can use TELNET command. In the start "Start" \ "Run..." dialogue box, type:

TELNET localhost 25

Name of the occupation will be displayed in a window that must look like this:

Alternatively, you can change port to be used by Autoroute SMTP to any other (within the range 1..65535) on the Internal Server tab of the program settings window. Please note that default port used by mail clients is 25, so you will have to modify your mail client settings as well.

2. Why do changes in setting sometimes take effect with several second delay?

Each time you change the settings, Autoroute SMTP recalculate IP-addresses of SMTP servers. Normally this takes up to 1..2 seconds. The program reacts to entering or exiting the net with the same delay, as well.

3. Can the program work with any servers other than SMTP?

The program is independent from SMTP protocol, as in fact it sets port mapping of the chosen server to a local port. Therefore it is able of routing any protocols that use one TCP-connection, e.g. HTTP-proxy. Please note that if port is not specified for any server in the list, the program will map port 25.

4. Can I use the program from a remote computer?

Yes. By default, the program allows connections from local computer and local are network computers only. When configuring mail client on a remote computer through your Autoroute SMTP, ensure that its address is included into Allowed IPs in the program settings. Besides, you should you your computer name or IP address (not localhost or 127.0.0.1) for outgoing mail server (SMTP).

5. Why does it suggest establishing Internet connection when the program is being launched?

This might take place if your computer is connected to a local area network and has a network interface with a fixed IP address. To solve this problem, use the option Don't resolve addresses within LAN or/and Don't resolve addresses when no dial-up connection on the tab General in Autoroute SMTP settings. Another way to solve this problem is changing your dial-up networking settings.

6. How to use multiple configurations of Autoroute SMTP?

Run ARS with -CFG key. E.g.:

AutoSMTP.EXE -CFG:myconfig1

AutoSMTP.EXE -CFG:myconfig2

AutoSMTP.EXE -CFG:strangecfg

In this case, program will read/write settings from different Windows registry pathes.
