To enable open relay, follow these steps:
1. Open the root.controls.lock file.

Changing Tomcat Java Connector Ports
The default port numbers for Coyote and Warp connectors in Parallels Plesk Panel are 9080 and 9008.
If you want Tomcat Java to work on other ports (e.g. 8090 and 8009), you should connect to the Parallels Plesk Panel database and add two parameters to the database as in the following example:
insert into misc (param,val) values (’coyote_connector_port’, ‘8090′);
insert into misc (param,val) values (’warp_connector_port’, ‘8009′);
Note: It is recommended that you change the Tomcat Java ports right after Parallels Plesk Panel is installed on server, or prior to enabling the Tomcat Java service for your domains.
Including Directives into Web Server Configuration File - Plesk
Note: you can change the location of virtual host directories using the transvhosts.pl utility, which is located either in /usr/local/psa/bin/ or /opt/psa/bin/ directory, depending on your operating system.
You can include domain-specific Apache configuration directives into web server configuration file. In Parallels Plesk Panel, each domain has virtual hosts configuration stored in a separate file httpd.include.
On all Linux systems, this file is located in the directory /var/www/vhosts/domain-name/conf/.
On FreeBSD systems, this file is located in the directory /usr/local/psa/home/vhosts/domain-name/conf/.
To use custom directives or redefine those inserted by Parallels Plesk Panel, you need to create the files vhost.conf or vhost_ssl.conf with necessary directives in the directory /path_to_vhosts/domain-name/conf/ for a domain, and /path_to_vhosts/domain-name/subdomains/subdomain-name/conf/ for a subdomain.
