Here's a patch which works towards a couple of goals.

The idea is to attempt to prevent mail loss when exceptional
events that KMail was not designed to handle occur.

In order to prevent mail loss when an external application
(like procmail) modifies folder files in ~/Mail I want to
check for an out of date index file everywhere that the
index file is updated which is in three places.

1) When closing (for real) a folder
2) When adding message to a folder
3) When compacting a folder

 
There's also the possibility that an external program
modifies a folder file but doesn't update its date, making
the kmail index file out of sync with the corresponding
folder file. I want to check for this, and if it occurs
then no longer compact that folder file (disabling
compaction should eliminate the possibility of losing mail
due to an index file being out of sync).
 
I have two ideas for doing this.
 
1) Check that the index entry matches the folder file when
a message is selected and if not disable compaction for
that folder (I've done that in the attached patch, it would
be best to prompt the user asking if they want to regnerate
the index file).
 
2) When compacting check that the index entry matches the
folder file. I'm working on a way to this quickly.

Specifically my changes to prevent mail loss by 
unsuspecting procmail users.

You can revert these commits and kmail will work again.

It seems (many if not all) nfs file systems are 
fundamentally broken and report incorrect file times.

I'm still in the process of deciding what the full 
repercussions of this discovery are, and what should be 
done.
