Cannot set up IMAP account on Yahoo mail with El Capitan.
Cannot set up an IMAP mail account on Yahoo mail. Auto set up defaults to a POP broadband incoming server with no way to change it. Yahoo IMAP worked with Yosemite and worked for several weeks after upgrading to El Capitan until IMAP account stopped connecting to Yahoo server.
MacBook Pro (Retina, Mid 2012), OS X El Capitan (10.11)
