What exactly will that save you from?  If the root FS gets messed up then 
having a separate /boot won't gain you much...

I suggest creating /home/mail and linking /var/spool/mail to it.  However 
if you want decent performance for email you want to use Maildir.  By 
default maildir storage goes into user's home directories which solves 
this issue.

If you have two partitions on the same physical media (in this case a 
RAID-10) then expect to lose performance.  If you make it all one large 
partition then the file system drivers can optimise things more.

I recommend having a separate /home to limit the things that can go 
wrong.  I recommend leaving /var on the root file system unless you need 
a lot of space in /var.  Also consider a separate file system for 
/var/tmp and make /tmp a sym-linke to /var/tmp/tmp .

RAID has no relevance to the issue of partitioning in this sense.
