Because SANs become a pain when you want to implement shared storage
(ie, one central mailspool mounted by muliple systems).  Certainly,
it's doable, but you have to have software running on all the systems
to deal with concurrent access.  I've yet to find a version of
this software that runs on Linux (or any other Open Sourceish OS),
so it's not even a consideration for me.

Well, you just need to be careful.  NFS security is resonably well
understood.
