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[23], 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.
