DynDNS and Zimbra

[afterwego]

So I tried to do the virtualhost method, by creating a virtual host that used the mod_proxy to forward it on to my mail server, however that didnt work.

So I checked out some of the tutorials on the wiki and none of them seemed to work either for using mod_proxy.

Are there differences in Apache2 install from distro to distro? I wouldn't think so, but thats the impression I am getting from these tutorials.
