The problem is that postfix will see "success" initially: - client sends - postfix receives - postfix relays, gets OK ----> postfix deletes queued message - exchange checks quota, decides mailbox is full - exchange sends DSN to client Worst case, client just spent 30 minutes on dial-up trying to send his 10MB in images my client needs. -- Melvyn Sopacua m...@dnr.servegame.org FreeBSD 7.1-STABLE Qt: 3.3.8 KDE: 3.5.10
