Right so store data correction in your database. Then you don't have to
look through that database, it just corrects itself. Of course
this makes the files a lot larger(about 3 times) but what's the
total size of all files under /etc, maybe 10MB for a large system.
Not a big deal.

The API will be open.

OK. But you must admit sendmail is a much more mature piece of software
than exchange. Fundamentally exchange will always be feature driven.
This never produces good software. Need driven software does.
