I have install zimbra zcs-3.1.0_GA_279.DEBIAN3.1 in Debian Sarge 3.1
then I'm trying to install and run xampp (apache, mysql,etc)
when execute /opt/lampp/lampp start
XAMPP: Another web server daemon with SSL is already running.
then stop xampp,
I attempt change port 443 to 4443 with
su - zimbra
zmprov ms <servername> zimbraMailSSLPort 4443
tomcat stop
tomcat start
connect to https://servername:7071/zimbraAdmin/ ok
connect to https://servername refused
then nmap localhost but port 4443 no appear

How to change port 443 to listen in others port, to solve this problem with Apache SSL (xampp)?
Thanks, and excuses my english, I only speak and write spanish.
