i am afraid i wasnt total corect here
in fact i havent seen backscatter overquota on my servers
since using dove lmtp with postfix

but i guess there may cases left in which it could happen
you should ask Timo for exact tec answer

the postfix answer ever was write some policy daemon for it
( which i found extremly complicated at my try, and stopped it )

but i guess its always a problem comparing
the size of a mail with space left in mailstore
i.e with many reciepts of one mail etc, whatever tec solution is used

so i should have said dove lmtp is the best/easy solution
for overquota i know at present and my problems with it are solved for now
