Testing Spam Rules
You can use Telnet or any mail client to test your spam filter rules and content filter policies. The results can be viewed in real-time from the E-mail VirusWall computer using the E-mail Monitor.
To create test emails using Telnet,
1. Open Telnet and click Connect | Remote System to bring up the Connect dialog box.
2. Enter the name of your SMTP server in the Host Name: field, and enter 25 in the Port: field.
3. Click the Connect button.
4. Click Terminal | Preferences to set Local Echo and any other preference settings you may desire.
5. At the "ready" prompt from the SMTP server, enter the following:
MAIL FROM: (true From address)
RCPT TO: (true To address)
DATA
From: (Enter false email address)
To: (Enter false email address)
Subject: (Enter test subject)
Message text: (Enter the message text that you want the content filter to check here...
The spam filter checks only message header information, i.e., that which appears above Message text and below DATA. The content filter checks data appearing in both the message text and header areas.)
The information entered in the first two lines, MAIL FROM: and RCPT TO:, should be genuine (Content Management does not consider these two fields).
Spammers seeking to cover their tracks will often expand upon the principles shown here to add false header information in an attempt to elude detection.
