How to close open ports ? ( without Netfilter rules )

[Eno]

Hello, I used nmap on my Zimbra test machine :

22/tcp    open  ssh     OpenSSH 5.1p1 Debian 5 (protocol 2.0)
25/tcp    open  smtp    Postfix smtpd
|_ smtp-commands: EHLO zimbra.test.local, PIPELINING, SIZE 10240000, VRFY, ETRN, STARTTLS, ENHANCEDSTATUSCODES, 8BITMIME, DSN
80/tcp    open  http    Apache httpd 2.2.9 ((Debian) PHP/5.2.6-1+lenny3 with Suhosin-Patch)
|_ html-title: Index of /
110/tcp   open  pop3    Zimbra pop3d

8585/tcp  open  http    Zimbra http config
|_ html-title: Zimbra Collaboration Suite Log In
10015/tcp open  unknown

In my mind there are too much open ports, is there a way to close them without adding rules in Netfilter ?
Lot of those ports are associated to services I don't use anymore, such as ClamAV, Spell checker ect ...

Check if you have antispam, Antivirus running. Stop and disable them.

Moreover something seems to be odd here : -

993/tcp open ssl Microsoft IIS SSL
995/tcp open ssl Microsoft IIS SSL
7071/tcp open ssl Microsoft IIS SSL

Can you explain how are these services related to single service and that too ms IIS server ? Are you sure you are running only zimbra on this machine ?

It's just a banner grabing by Nmap, nmap guess the service behind the port.
