mac mail will not display
I am currently using mac mail 6.2.
Working fine upto today. Now it tells me I am receiving message but they will not display.
I can send messages but they don't show up in the sent file.
My service provider assured me the settings our correct and it's working fine on my i Phone.
Any suggestions out there?
mac mail 6.2-OTHER, OS X Mountain Lion (10.8.2)
