This is almost exactly what I've been looking for/designing for
official mail outs to multiple users on the system. I was going to try
a system, of putting a message in a shared box (using ACL's to control
who could write to that box), and then having a runner check the box
once an hr or something, check the specially crafted To: header, which
would do a DB lookup and then start runners hardlinking the file
(after moving to a processing tmp box) into all the (correct folder)
Maildir's of the recipients. The idea being to create a sort of
mailing list, for official mail outs to the different sections of the
organisation.
e.g. To: accounting-group at host, committe-group at host
With each group expanding in to possibly hundreds of users, based on a
lookup, and only 1 copy stored on the system.

I think for what I'm doing, I might still have to implement the runner
system or try and generalise the groups more, and use shared folders.
But still, if a user sends the same email to 50 people, having
dovecot-lda detect this, and only store one copy, would be a bonus!
