Problem
You installed a Symantec Brightmail product, a Symantec Mail Security for SMTP 5.0 product, or you set up a Symantec Brightmail Gateway appliance. You need to know how to test mail flow and spam detection. This KB does not apply to the SMS 8100 or Symantec Brightmail Traffic Shaper (SBTS).
To test some of the new non-spam dispositions on Symantec products check Testing newsletter, marketing mail and suspicious URLs dispositions
Solution
You can test mail flow and spam detection in a variety of ways. One way is to use Telnet to create an email and send it from an external source. In the email message, add at least one of the following:
- In the header of the mail message insert the following:
X-Advertisement: spam
- In the body of the mail message insert the following URL:
http://www.example.com/url-1.blocked/
- In the body of the mail message insert the URL:
http://www.example.com/URL-2.blocked/
Note: Disable SAV Email Auto-protect before testing. The test strings do not work for Symantec Mail Security for SMTP 5 in Basic AntiSpam mode. The test strings do work for Premium AntiSpam mode.
To send a test message using Telnet
- Open a command prompt.
- Type the following command to open a Telnet session:
telnet
whereis the host name or IP address of the server and is the correct port number to use.
- Type the following command:
helo example.com
The correct returned response is as follows:
250 OK
- Type the following command:
mail from: test@example.com
Do not use the domain you installed the Symantec Brightmail product to as part of mail from line. Use an alternate domain for the test. If the installed domain is, run Telnet from an alternate domain like . This change ensures that you do not accidentally bypass Symantec Brightmail AntiSpam.
The correct returned response is as follows:
250 OK - mail from
- Type the following command:
rcpt to: your-address@your-domain.com
Make sure that you use an email address that you can check for your-address@your-domain.com.
The correct returned response is as follows:
250 OK - Recipient
- Type the following command:
data
The correct returned response is as follows:
354 Enter mail, end with "." on a line by itself.
- Type one of the following lines and any additional text that is needed (end with a CRLF.CRLF):
Subject: Spam Delivery Test
X-Advertisement: spam
spam test
.
The correct returned response is as follows:
250 OK
221 Closing Port / Mail queued for delivery
- Type the following command:
Quit
This command stops your telnet session. This example should be sent and received by your downstream server. The URL in the message should be treated as spam. The default action is to prepend the text [SPAM] to the subject line.
Technical Information
Telnet is a terminal client. This client provides a remote interface to a computer and enables you to create a session to any text-based protocol. You can use a Telnet session to manually send a test email from a command interface. You can use this session to determine the errors that occur during that process.
Examples of text-based protocols are SMTP, HTTP, and POP. To use any email client, set the outgoing SMTP server to the IP address of the Symantec Brightmail server.
