Indeed, it could generate some latence on mail delivery due to the SQL requests.
I tested it on server that handles about 10 000 a day and there no serious impact.

To avoid performance implications it will be better to have a dedicated table updated at same time that statistics and that will reduce query time.
For now it's not, because my restriction was to not change a lot of PMG core code/structure.

I understand you no-go, the Quota filter will be soon available on my Github as patch that could be applied on PMG for whose want to accept the performance implications.

Maybe, but this patch has serious performance implications. Seems there is one 
big slow database query for each email address, so that is a no-go. Someone already
done benchmarks with this patch applied?
