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.
