Connecting Remotely to MySQL

I have recently setup a Red Hat 9 server with a Plesk 7 control panel on it.
On my old server I could connect to the mysql DB with a program like mysqlfront by connecting to the IP address or domain name. Now however on the new one i get an error message along the lines of "Connection failed: 2003 - Can't connect to MySQL server on 'ismfa.com' (10060)".
I am a newbie at setting up a server so can anyone help me please.
