For a couple of weeks now I'm having trouble with Mail on all OS X devices I use, iOS does not seem to be affected though. The application becomes unresponsive right after I start it up showing non of my emails. I have so far tried all recommended fixes I could find in different forums from booting in save mode and opening the app to restoring the different mailboxes and manually reindexing ... it would only work for a while before I run into the same problem again and again, so a certain amount of time each day goes to finding a fix and trying to fix this problem. Can anyone come up with a solution besides using another mail client or reinstalling every device?
