Toto by som zdaleka nenazyval mail klientom nakolko toto su podmienky instalacie:

Web server: Apache, NGINX, lighttpd or other with PHP support

PHP: 5.4 and above

PHP extensions: cURL, iconv, json, libxml, dom, openssl, DateTime, PCRE, SPL

Toto je uz u mna server a nie klient. A uz vidim ako ho spusta na inom pc cez web;o).

Vyborny je aj popis instalacie.

Extract files from RainLoop Webmail archive and upload those to server.

• Set correct permissions for files and directories.

• Configure web server to prevent accessing configuration files via web browser.
