[SECURITY] Fedora 28 Update: mailman-2.1.29-1.fc28

Mailman is software to help manage email discussion lists, much like Majordomo and Smartmail. Unlike most similar products, Mailman gives each mailing list a webpage, and allows users to subscribe, unsubscribe, etc. over the Web. Even the list manager can administer his or her list entirely from the Web. Mailman also integrates most things people want to do with mailing lists, including archiving, mail <-> news gateways, and so on. Documentation can be found in: /usr/share/doc/mailman When the package has finished installing, you will need to perform some additional installation steps, these are described in: /usr/share/doc/mailman/INSTALL.REDHAT
