[Dovecot] SQL as a storage backend

Hello,

I am researching using dovecot with an SQL database as the storage backend. From what I've read, dovecot only supports mbox style file storage, but I'd like to investigate the possibility of using a database instead.

According to http://dovecot.org/pipermail/dovecot/2006-June/013818.html, this possibility has been explored before and has generally been accepted that Dovecot is not optimized to handle this.

Any suggestions?
