[Dovecot] MySQL as a storage only.?

[Romer Ventura]

Hello,

    I was wondering is I could use MySQL as storage only..? Meaning that no
user information, other than the obvious email address associated with an
specific email so that each email can be showed to the right user, will be
stored in a MySQL database instead of /home/vmail/DOMAIN/<user>

    Would I get any advantages.? Would it be better, faster?

Thanks
