I just got done rebuilding my iMac (Late 2007) and after the Time Machine restore, I opened up Mail and it said it had to re-index all my mail messages. I clicked OK and now when I got into mail, I see all the subject lines for all my mail but when I open each one, it is blank. I then look at the email online with my ISP's mail program and the whole message is there. I looks like a message "placeholder" is on my computer but the content is still on the server. Is there a way (easy) to get Mail to re-download all the mail messages from the server to my computer?
