Yum autoupdate sends email to "root" about updates performed. Perhaps that is the reason it is looking for mailx. It uses mailx in a scripted mode to create the messages.

Hello! Line 211 of /etc/cron.daily/yum-autoupdate calls /bin/mail, but yum- autoupdate-2-2.noarch does not depend on anything providing that file (mailx-12.4-6.el6.x86_64). This seems like a bug in dependencies, or is there a reason for this? Kind regards, Dennis
