Are you running a MailCleaner Anti Spam Gateway on your network? If that is the case, you may have other systems that could benefit from directly connecting to the MySQL instance on you MailCleaner Server. Below is our MailCleaner MySQL configuration script that will set the MySQL root password and add the proper firewall rules to allow remote access. In order to use the script below, edit the script with your desired root_pass and access_subnet and the copy the script to your server and make executable.
#!/bin/bash
#
# mc-mysql-remote
#
#
# set custom variables
root_pass='your-root-password'
# for access from anywhere set 0.0.0.0/0
access_subnet='your-access-subnet'
# variables don't edit
