In other words, this isn't a bug but postfix reacting to a "faulty" filename. There shouldn't be a dot at the end. You might want to check your /etc/hosts and/or /etc/hostname. You probably also want to make sure the faulty name hasn't ended up in /etc/postfix/main.cf. ** Changed in: postfix (Ubuntu) Status: New => Invalid -- package postfix 2.6.5-3 failed to install/upgrade: https://bugs.launchpad.net/bugs/518281 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to postfix in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
