The relative merits of storing mail in a relational database is a recurring
theme on this and one other list I attend (Dovecot). I think the conclusion
is that it may have benefits w.r.t. organising and indexing mail, but that
the performance of simple maildir storage can't be beaten.

First and foremost you will need a POP/IMAP (I assume you will provide IMAP
access, otherwise using a RDBMS seems rather pointless) server that can serve
mail from a database, for example DBMail (I don't know how good it is).
Whatever your choice, its documentation should tell you how to setup MySQL
(or PostgreSQL).
As far as Exim is concerned, it simply needs to be able to hand off the mail
to an LDA, either over LMTP or by piping it to a program (DBMail supports
both). Additionally, you'll want to query the database directly so that Exim
can know if an address is valid.
