	I have attached our doveconf -n output. We have two imap servers (with 
the same configuration) and two more acting as proxy (with director) in 
front of them. These last direct user request to their corresponding server.

	For storage we are using our SAN (a HP 3PAR 7400) connecting to it with 
fibre channel. We have two XFS filesystems. One for mail indexes and the 
other for user mailboxes and attachment files.

	In these servers we are running ubuntu 12.04 with kernel 3.4.0.

	We are using horde.
