Mail Monitor

The Trilent Mail Proxy includes a simple mail monitor, capable of monitoring a single e-mail connection. This is useful for troubleshooting or simply to observe the mail protocols (SMTP/POP3) in action.

To start the mail monitor, click on the "About" tab of the control applet. The screen will look like this:

Click on the "Monitor" button. A dialog box will apear:

Press the "Start" button to begin monitoring mail. A console screen opens that will echo any mail session. The direction of the mail transmissions is represented by the text color, as shown above. Here is an example of a short POP3 session (checking for incoming email) as shown on the monitor screen:

Waiting for messages..

Trilent Mail Proxy started.
POP3 connection opened by client 192.168.0.3.
+OK QPOP (version 3.21beta1) at pop3.example.net starting. <139.1129870433@pop
3.example.net>
USER john
+OK Password required for john.
PASS mypassword
+OK john has 0 messages (0 octets).
STAT
+OK 0 0
QUIT
+OK Pop server at pop3.example.net signing off.
POP3 connection closed.

Press "Cancel" to exit the monitor.

Note: Since only a single mail connection can be monitored, the mail proxy will be started in a single-connection mode that allows only one mail connection at a time. (Normally, the mail proxy supports 30 simultaneous mail connections.)

If the mail proxy service is already running, it will be stopped and then restarted in the single-connection mode. In this case, the following dialog box warns you of the danger of terminatating any ongoing mail connections (and annoying other users.) Clicking on the "No" button exits the monitor.
