What platform have you installed this on ?
By default, the URL (as Rachel said) should be
http://scalix.bluemike.com/Scalix/rw.
The Rules Wizard doesn't use tomcat so you should be able to enter that URL into the browser and have the Rules Wizard login screen displayed.
If this doesn't get displayed, i.e. you get a 404
Apache error, this would indicate that the Apache configuration is not correct.
First of all, try stopping and restarting Apache in case the configuration changes that Scalix made were not picked up.
For RHEL and FC, there will be a file in /etc/httpd/conf.d called scalix-web-client.conf. This will be a symbolic link to /opt/scalix/global/httpd/scalix-web-client.conf.
For SuSE, the file /etc/sysconfig/apache2 should contain reference to /opt/scalix/global/httpd in the APACHE_CONF_INCLUDE_DIRS variable.
If this isn't present, try running the script /opt/scalix/bin/omwebconf. This should add the appropriate configuration settings. This will also stop/start Apache again.
Cheers
