RAID 5 is not a good choice for a MailServer. There are very long
discussions on that topic in the respecitive Usenet groups so I will
spare you the details. The break down is, that you will have around 50%
writes with a mailserver and RAID 5 scale up well to about 20% writes
versus reads.

Personally I would run a Mailserver using Raid1+0 but that is very
expensive as you will need an enourmous amount of disks and a very good
RAID Controller. RAID 1 is a good choice. A Good RAID controller will
compensate for the technical shortcomings and the security level is
extremely high :)
