I think there was a brief thread not very long ago, on webmail which
explains why this is an appalling idea.

I hope you never get messages of over 64k or headers of longer than 255
bytes.

This is a crazy idea for this reason.

The way to do this is not to do this directly throuh exim, but to write a
small program that reads the message and actually does the insert, such
that you end up delivering to a pipe, and then insert into the database
from this secondary process. Of course, MySQL doesn't have proper
transaction locking or record locking, and so you have some fun if your
mailserver is at all heavily hit.
