I suggest you XFS over a LVM of SoftRaid5 for Maildir storage, fast, stable
and scale very well.

I hope you are joking, that will be a madness.
It's pretty easy, just use procmail/maildrop as MDA of your MTA, I have
mailservers running Postfix and Qmail, and both use maildrop as MDA so I
could have a .maildroprc file on each user Maildir then a
general /etc/maildroprc that look if the destination user have a .maildroprc
file and include it.
On my MailServers farm, things are like this ... :
SMTPin Server -> StorageServer
PoP3/IMAP Server <-> StorageServer
SMTPout Server <- StorageServer
WebMail Servers <-> StorageServer
I have a bunch of StorageServer in a similar fashion like a SAN, but done over
LinuxServers serving files over GFS to "utility servers", then StorageServers
uses 3Ware9500 S12 inside a Supermicro 933 chasis, other StorageServers does
not have 3Ware hardware (that ones are 4 years old servers), new servers uses
LSI SAS-SATA controlers and SoftRaid instead of HardwareRaid, they are
cheaper to mantain and cheaper to repair.
