I am setting up The Perfect Server - CentOS 5.3 x86_64 [ISPConfig 3]. I am following the guide but are having issues when trying to install software through yum. yum install amavisd-new yum install clamav yum install clamd I get "No package 'the package name' available" for all 3. Does this mean the mirror I'm connecting to does not have the packages and is it possible to use another mirror to install them. If I can use another mirror how do I do that please. Thanks in advance.
