Apple Email "From," and "Subject" lines do not match body of email
After on and off problems with the imap server in iCloud the past couple weeks that prevented me from getting my .mac mail anywhere other than on the iCloud website, my inbox has morphed into a jumble of miss-matched Email Subject, From/Sent by, and Email Body. In other words I will double click on an email that appears to be from my niece, but when it opens it is actually an email from Amazon - or someone else! I am done with MAIL, but need HELP restoring my inboxes. I have "Rebuilt" all inboxes but it didn’t repair the problem. I have since switched to Outlook client for Mac and the problem does NOT occur with Outlook.
Ideas?
