can not set qmail quota higher than 2GB?

[fran@]

I tried on various versions of Plesk:
8.2.1, 8.1.1.
they all have the same "bug":

whenever you set up a value > 2Gb in Plesk for the mailbox quota,
the qmail @mbox.quota is set to 2097151
Values stored in Plesk CP and database are correct.

Setting quota works fine for values < 2GB
We have but a few mail users who WANT a 5 GB mailbox, but we'd like to give it to them.
