I am running OS X 10.7 and I am trying to setup Mac Mail with yahoo. I can send, but no email is showing up in the inbox. I setup the same account in Thunderbird, and all flows like wine to the river nile. Tried changing views, changing ports to custom and setting it at 587. 465. Even tried it as pop, still no emails are showing up. I don't get any errors that would indicate a bad setup or configuration. Could Icloud account affect this? I was thinking of maybe removing her Icloud account, but I have some apprehensions about her possibly losing her contacts etc.
