firstly I must tell you, that I´m a linux newbee and I try to get some experiences. So I installed "The Perfect Server - Debian Squeeze (Debian 6.0) With BIND & Nginx [ISPConfig 3]".
Instead of postfix I have installed this mailserver http://www.b1gmail.com/en/infos/addons/b1gmailserver/
and everything works fine - the only thing which doesn´t work is receiving systemmails and sending phpmails.
Therefore I would ask if somebody can tell me what I have to modify in the configuration of ispconfig or of nginx.
thank you very much in advance.
