Deleting "/home/user/.qmf" ONLY deletes emails, right? I don't want to delete my text (sms) and skype and gtalk messages. But is not a big deal if I delete my gtalk messages. Googlemail on my N9 has stopped syncing to the IMAP server. I removed all email accounts on the N9 and then did a backup, but I see that my backup contains 200MB of emails. So when I restore the backup the email files get back to the phone and the phone still doesnt sync to IMAP. I would like to remove all email data and only email data from the phone.

Thanks for this thread !
