Me too, Blueyonder is truly the worst mail service there is, if it's not down for maintenance it declaring are you a robot, that is if the blessed programme will actually load and open, now it wants me to enable Java script which is the back door to all sorts of nasties!
Unfortunately I have to have Blueyonder as I am with virgin and need it for them to correspond with me, but they do not want me to get in touch with them, weird company they are!
