Give the OP a break, it seems he is trying to put together an integrated tool set, rather than general-purpose components. In an integrated tool set one sometimes sacrifices flexibility in the name of inter-component integration. The database abstraction may come along later, or the tool set may essentially be an application-specific extension of the required embedded database. Vertical products (say like Zimbra) built around Postfix are a good thing IMHO, we need both general purpose components for DIY administrators and integrated products for users who want a complete system. -- Viktor.
