Webmail can attract lots of hackers. So my goal is to limit their access to Webmail by the standard Apache htaccess method. I have done it successfully for the Apache2 web sites access and also the ISPConfig 3 control panel. However, I am not successful on limit access to ISPConfig 3 SquirrelMail. The htaccess method does not work on Squirrelmail. Is anybody successful on this? Could you share with us? My system is ISPConfig 3.054sp1, webmail is Squirrelmail, installation follows the ISPConfig 3.05 Manual, the htaccess file is at /usr/share/squirrelmail/.
