We manage ~100K mailboxes which will be migrated on new servers. The

XFS.
Some time back I did some benchmarks with "mailstone", and decided in
the end to go with XFS on Linux. JFS was also fairly good. Now there
is ext4; haven't tried that for mail, it's still somewhat
experimental. I used it on Fedora 9 for a while but things crashed
(possibly unrelated) and the absence of ext4 support in the rescue
disk killed me. It did seem significantly faster than ext3.
Since then, we tried using XFS on iSCSI which was a disaster, at least
under RHEL 4.
RHEL6, currently in beta and due towards the end of the year, has
builtin support for both XFS and EXT4. I am looking forward to testing
these as replacements for my conservative, but fully functional, EXT3
over iSCSI on RHEL4 setup.
fyi,
David
