We are using xfs.
I tested xfs before going back to reiserfs. I found the performance to
be acceptable aside from quite miserable backup performance once backups
kicked off. (Although reiserfs is now pretty miserable,

My guess: ext3. ReiferFS has some very annoying weaknesses that may
affect you.
Please specify those weaknesses. 250,000 mailboxes on reiserfs right
