Ok, the bug is that external filestorage for big payloads on the akonadi server
are not enabled by mistake. That means even big mails are (temporarily) stored
in the DB, and the DB doesn't support that. We'll fix that bug in the akonadi
server soon.

Hmm, I actually can't reproduce this. The information of the already downloaded
mails is stored in $KDEHOME/share/apps/kmail/<login>:<host>:<port>, in that
file you'll see an entry "seenUidList" and "seenUidTimeList". Those two entries
are the list of already downloaded mail. For me, the settings got sucessfully
migrated and are now found in
$KDEHOME/share/config/akonadi_pop3_resource_<number>rc.
