Hey Steve,
I'm not sure what your question is, you seem to not want to
do RAID 5 and can't do RAID 1+0, that leaves RAID 1 if redundancy
is required. Were you mistaking RAID 1 and 0?
Basically the only question you really need to ask yourself is
how much mail you'll end up storing? If you're going to
eventually store more mail than the largest pair of hard drives
you can afford right now, then RAID 1 won't be an option that
will let you easily grow later, you'll need RAID 5 so you can
start small now and add disks as needed. I'm sure any decent
RAID 5 controller can pump data out fast enough to saturate
a fast ethernet segment with NFS reads from your POP3 servers.

I've searched the archives extensively, and I've learned quite a lot, but
I'd like advice on this question:
Assuming RAID 1+0 is not an option (due to the expense), what level of
RAID is best for storing /Maildir's on a file server (that will be
accessible to the SMTP & POP servers via NFS). Redudancy is the big
issue, otherwise I'd go for RAID 1. The suits are pushing for RAID 5
because they don't know better - and won't listen.
Steve.
