[Exim] SMTP Logging

For business reasons which include the need to run advanced SQL querries
against a large email archive, I need the ability to somehow commit email
messages - including header <AND> message body - to a MySQL database. I'm
willing to go at this just about any way, but I'm having significant trouble
finding ANY method to log the message body of an email.
