Mac Mail not getting email

Suddenly Mac Mail is not getting putting any email in my Inbox on my MacBook Air w/ Mountain Lion. I get my email via Go Daddy email service and using IMAP. I do get email that was in folders such as Sent Items, and Drafts.
I have deleted the email account numerous times. I have deleted the sub-folder of the account in ~/Library/Mail.

I setup the account successfully on my Mac Mini.

Any suggestions to get my email flowing back to my Inbox is appreciated.

 

Thank you askees.

The rebuild option for me is grayed out. Do you know why?

Edit: I was able to setup a Gmail account successfully and get email into my Inbox.

Edit #2: I just installed Thunderbird and all of my email is coming in.

Edit #3: I have no problems sending email via the GoDaddy account.
