I am not using mysql.  I use sqlite3 which the KDE devs say it's not up to the 
job (can't handle the multi-threaded-access/read/write that mysql does).  So I 
have the sqlite USE flag enabled.  Akonadi and nepomuk started but never 
managed the migration.  No sqlite errors on the terminal that I started kmail 
from.

BTW, this is not a suggestion to use sqlite!  If you are happy to run a full 
blown mysql database on a desktop machine carry on with mysql or postgress.  I 
use mysql on a production box, because it's already running mysql for some 
other apps.  However, on this old laptop I'm using sqlite because this is an 
asthmatic PIII laptop with rather limited resources.  I don't need/want 
desktop semantic tagging, GUI search, or any of the new KDE design philosophy 
features and functions (find and egrep have served me nicely for years now, 
thank you).  Kmail 3.5 was fine, stable and relatively light footed.  It met 
perfectly my needs.  :-(

You will need to restart the migration process.  For this you will need to 
shut down nepomuk and akonadi.  Then remove their respective config and db 
files.  Then restart them and fire up kmail afresh.  You'll have to be patient 
though, assuming the migration starts correctly this time.  Read more here:

http://userbase.kde.org/Akonadi_4.4/Troubleshooting

If not, then remove their files all the same, restart them and proceed to 
importing the mail directories from your Mail one at a time.

They are usually imported in a kmail-import.0 type of folder.  You can rename 
that, or select any subfolders and move them where you want them.

On every such physical move you will have to be patient.  Small subfolders 
will move and the akonadi with resync its tables within a few seconds, but 
larger folders with thousands of messages will take ages to complete.

After the whole import, sync, move, sync process has completed things will 
move smoother (only a few seconds delay when you open or access a large 
folder).

This is a game of patience.  It helps if you imagine sloooowly ringing the 
neck of those devs who released this half baked piece of C.R.A.P. on us.  
(Cannot Retail at Any Price).

I suggest you try one move at a time and then wait until it finishes.  
Completely.

Yes, there may be a couple of seconds delay between large folders, when kmail 
first starts.  Fewer seconds lag after the first time.

Not all of my maildir ~/Mail folders were picked up.  I had to import these 
manually as recommended in the Gentoo guide for the migration.

I recommend that you mask KDEPIM-4.7 with the packages kindly offered by the 
gentoo devs:  http://www.gentoo.org/proj/en/desktop/kde/kdepim-4.7-mask.txt

I've upgraded KDE on two boxen, but masked KDEPIM-4.7 as recommended and had 
no problems so far.

I have tried Claws (although I did not like mbox) and found myself cursing 
after every other key press.  I also tried T'bird and found it better than 
Claws, but worse than Kmail.  It's not just keyboard short cuts, but also how 
it integrates with the address book, pgp and s/mime, etc.

I started looking into getting used to mutt again.  Not sure how I can modify 
its shortcuts, because some them are not intuitive enough for me and some are 
duplicated/redundant.
