Yesterday I tried to send a Quicktime movie that I made with iMovie as an attachment to an email. I knew something was wrong when it kept "sending" for hours. I could not get it to stop, no matter what I tried. I used Force Quit on Mail: no effect on the spinning circles. I shut the computer down and then restarted. Signed into Mail--> still had spinning circles. I took the mailboxes offline and then put them back online: spinning circles remained. I deleted all of the outgoing messages several times, but whenever I came back, they reappeared. I shut off my computer overnight. This morning the spinning circles are gone, and a static circle remains, and I am unable to send or receive email. What can I do? I have four Mac mail accounts and they all have important information in them. How can I unfreeze my mail? BTW, the gmail accounts that go to the mac account are ok--it is just the "@mac.com" accounts that are frozen. I can not find this in a search. I would really appreciate some help with this.
