MySQL question

Mmkay, well i'm testing out my own website(woooohooo x.x ) but of course, i'm retarted.

So I used Nmap to see what came up, and found all this:

21/tcp   open  ftp?
22/tcp   open  ssh         OpenSSH 4.0 (protocol 1.99)
25/tcp   open  smtp        Sendmail 8.13.6/8.13.6
80/tcp   open  http        Apache httpd 1.3.34 ((Unix) PHP/4.4.2 FrontPage/5.0.2
.2510)
110/tcp  open  pop3        UW Imap pop3d 2004.89
143/tcp  open  imap        UW imapd 2004.357
443/tcp  open  ssl         OpenSSL
513/tcp  open  tcpwrapped
514/tcp  open  tcpwrapped
554/tcp  open  rtsp?
3306/tcp open  mysql       MySQL (unauthorized)
7070/tcp open  realserver?
8080/tcp open  http-proxy?

The only thing i'm really worred about is the MySQL, which says "Unauthorized" Any ideas?

Nothing to worry about, the port is only open so you can connect to the MySQL server from another web host.

Nobody can hack it unless they have a valid user/pass (or are willing to attack the login).
