f24 postfix install DNF messages?

The subject line had an unfortunate typo the last time I sent this. Let's try again with a fixed subject and see if anyone can tell me what the heck this means :-). Running dnf install to pick up loads of things for my new f24 partition, this nonsense appeared: Installing : postfix-2:3.1.0-1.fc24.x86_64 1088/3005 The unit files have no [Install] section. They are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...). Installing : qmobipocket-16.04.1-1.fc24.x86_64 1089/3005 Is this trying to tell me I can't run postfix as a service? If so, why not? If not, why did it want to print this gibberish and confuse me?
