I'm trying to find a Webmail that I can install on my Web Host (the host had PHP and MySQL, no access to apache config or php.ini except by .htaccess and some configs in local php.ini file).
I'm currently redirecting my emails to gmail but I want to stay more in control of my things. So I'm looking for something like gmail, OpenSource with a good community behind it for security fixes and update, that can be installed on my Web Host. I found something interesting (http://www.zimbra.com/downloads/os-downloads.html) but I need to install the app on the Linux server and it seems to be more than just a simple PHP application.
I don't even know if what I'm looking for is technically possible and if it exists. Any suggestion is welcome!
