Loose mailbox size policy doesn't work after upgrading to Plesk 12

[Frater]

Today I upgraded to Plesk 12 and during the day I got several customers that had problems with their mailbox size.
According to Plesk they were exceeding the size, but they've been doing that for years.
The setting that these limits don't have any real meaning is ignored after the upgrade...

Hi Igor!
Could you give a reaction?
