It would be very nice indeed.

"Someone" already stores mails in a database: Oracle (Email Server and
Collaboration Suite). I set up the Oracle Email Server 5.2 for a company I
worked for earlier. And to express it nicely: It was a nightmare! Mails
got stuck and rejected because the system was not capable of writing them
into the database. Besides, the support for that system was also =0. We
were probably the only ones daring to run the system ;-) I am glad I am
running cyrus now. Extremly stable and fast.
That system was not well thought through at all. I don't know how much
work needs to be done for a database email store, but Oracle wasn't
(isn't) able to do so.
