I somehow lost the use of kmail - couldn't send, couldn't download and lost my custom folders. I fooled around, reinstalled kmail, etc. Now, I can send and download, but no folders and no saved mail. From a backup, I restored ~/.kde/share/apps/kmail/mail/inbox, where the folders and mail were. However, kmail still has no mail and no folders other than the default ones. It's kmail 4.14.1. Any advice, pointers, etc. appreciated.
