As you obviously realise, this is the most common cause of losing messages - a 
corrupt index.  One thing to note.  Did you make sure that kontact was closed 
when you deleted the index files?

What's really confusing, though, is those messages apparently repairing 
themselves.  I've no idea on that.

Are the folders mbox or maildir?  Maildir is better speedwise, but also if 
something gets corrupted the rest are not at risk.

If you have the patience you could create some new subfolders and drag 
messages (many at a time, if appropriate) into them, ending up with more but 
smaller mailboxes.  KMail allows nesting, for instance this folder is Inbox > 
KDE-Lists > kde-pim, which makes it easier for searching.  I can search on 
KDE-Lists + subfolders, or on Fedora + subfolders, for instance.

Incidentally, drag'n'drop is also the way to convert folders from mbox to 
maildir - create the new folders, move the mail, delete any obsolete folders.

Don't we all?  I've been using Linux for more than seven years and am 
constantly learning.
