I'm unsure if this is recommendable. I'm missing a way to get rid of the 
smalle files.

Tried this with 
akonadi-runtime-1.7.2-121.2.x86_64
kdepimlibs4-4.8.4-289.3.x86_64

I've deleted a file from .local/share/akonadi/file_db_data/
which used to be a signed email. Afterwards it did not recover by itself.
Note even got a useful message as user, just that the crypto module did not 
return anything, but raw view showed no body of the email at all.

Using the akonadiconsole and "clear akonadi cache" on the folder and 
syncing again helped. But this is not feasable for all folders or a normal 
user.

Do people here agree that there should be a better failure message to the 
user? (If so, I may file a report for this.)

I've switched off a folder with some email that had entries in 
.local/share/akonadi/file_db_data/ using the local subscription.
However the file I was watching did not disappear.
When should it disappear?
If it does not disapper at all, I guess this would be an issue that I would 
report.

So I'll try deleting the accounts, stopping akonadi and then changing the
 SizeThreshold and adding the accounts again.

The 32764 file limit really is a limit given that my fuller desktop sync
of those accounts is over 220000 file in this directory.
