Topic: Ubuntu cannot resolve domains after iRedMail installation
This happened twice already for me so I'm pretty sure it's not a coincidence.
Basically I'm running a fresh installation of Ubuntu 11.04, set up LAMP and proftpd which is all fine, but right after I install iRedMail 0.7.2, the system is then unable to resolve any domain names, which means tons of things including apt-get does not work because the system is then only capable of using ip addresses. The files /etc/hosts /etc/hostname and /etc/resolv.conf seem to be in order. Any ideas why this is happening?
