I am running Snow Leopard with its latest updates. After I set-up my comcast.net email address in Mac Mail to the right of the Inbox it states how many unread messages I have it. The number is 1464 but I cannot see any emails. I sent new emails off of my phone and I can see the number of unread messages count higher and I hear a noise indicating new emails but I still cannot see any of them. It is the only email account in Mac Mail. What may be causing me not to see my emails? Thank you.
