[Dovecot] SQL as a storage backend

[Zachary Sturgeon]

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?
