[Dovecot] mail spool filesystem

[Julio Cesar Covolato]

Hi!

I´m about to migrate a system whith 5000 accounts whith (~ 500GB) from 
"postfix/courier-imap/maildrop/mysql" to a new hardware whith 
"postfix/dovecot/dovecot/mysql".

  I´ll make a separate partition (raid 1) for the mail spool 
(/var/spool/vmail) and want to now what type of filesystem to use on it 
to increase performance. I read that XFS is a good choice, but is not 
too reliable...

Any sugestions?

Thanks in advance,
