You should use a filesystem with dynamic Inode allocation. I use XFS - it is
incredibel fast and a journaling filesystem. It is even NFS-proof, so you can
export your vpopmail-home to multiple hosts.
IMHO you should not use ext, because hosting 1.500.000 emails, stored in
Maildirs, you will not see a good performance.
Reifers is also a filesystem with dynamic Inode allocation, but in my stress
tests it fails under heavy SMP-Load and it has problems with NFS. Last it was
unusable to be a cluster FS, because the standby host didn't see any file the
origin hosts sees.
So feel free to make your own tests - this is meant to be my experience.
