By default, Vibe imposes a limit of 500 message recipients for each email notification that Vibe sends. You might want to change this limit to 1 if you have configured Vibe as described in Configuring the Field that Vibe Uses When Sending Emails.
Change to the following directory:
c:\Program Files\Novell\Teaming\apache-tomcat\ webapps\ssf\WEB-INF\classes\config
Make a backup copy of the ssf-ext.properties file, which is located in the same directory as the ssf.properties file.
Open the ssf.properties file in a text editor.
Search for the following line:
Open the ssf-ext.properties file in a text editor.
Copy the mail.rcpt.limit=500 line from the ssf.properties file to the bottom of the ssf-ext.properties file.
Change 500 to 1, so that the line now reads mail.rcpt.limit=1.
Save and close the ssf-ext.properties file.
Close the ssf.properties file without saving it.
Stop and restart Vibe to configure Vibe to include only one user in each email notification that is sent.
