Run CGI scripts anywhere in the server + Plesk

Server wide :

cd /etc/httpd/conf/

cp -p httpd.conf httpd.conf.bak

vi httpd.conf

uncomment AddHandler cgi-script .cgi

service httpd restart

1. create an .htaccess file in your cgi-bin directory, that file should have the following

AddType text/x-server-parsed-html .html
AddType application/x-httpd-cgi .cgi .pl

Make sure you upload it in ASCII format, not binary.

2 set the permissions on your scripts correctly.. usually to 755

Stop Open Relay of Exim

Telnet to yourmailserver at port 25 and issue all the following commands:


telnet hostname/ip 25


mail from:

rcpt to:

If you are getting the error “554 : Relay access denied” then the server is not an open Relay

If not Just pass the command “DATA” sfter the recipient and then enter the message ending with a period ie : “.”

If you get the reply “SUCCESS Relay Accepted – final response code 550″

Then as you feared your server is subjected to open relay and if not enjoy………. It is not

I hope your server is not open relay supporting, but if it is so, as it is a Cpanel Server you can stop it normally using the below scripts



/etc/rc.d/init.d/antirelayd restart

service exim restart
