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 > >> >> >> >> -- Noel Jones > > -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
