MDaemon reports "POP server too busy"

MDaemon's POP server reports 'POP server too busy'.

If one of MDaemon's editor windows is left open, (Primary Domain, Account editor, etc...) MDaemon will not be able to reset the maximum POP3 concurrent session count and your users may experience warning messages in their e-mail client stating that the server is too busy try again later. Always make sure that the editor windows are closed when not in use.
