Hello, I recently installed on a dedicated server with ispconfig3 and centos 6.3 x64 for configuration I followed the guide on this site. Unfortunately the server does not receive the email and sends it. I also bought the guide configurezione on the panel from the reference site but have not found good solutions. The server manages about 90 different domains and email accounts for each domain. This situation limits me not a little in the configuration. Thanks in advance.
