So this device is NFS mounted, or shared-scsi? Either way is
potentially very dangerous. I remember working for a large company that
had a majority-site meltdown due to the primary NFS server dying. It
turned out the SCSI cable was chewed on by a rat.
FYI the linux-ha mailing list has lots of words of advice on either
topic in their archives.

If you're doing this on 1-2 servers then I am impressed with qmail. Not
enough to migrate from postfix, but to each his own. Maybe if I turn
into a spammer I will use it.
RE: spamassassin speed - it got a lot faster for me when I:
1.) switched spamasssassin to use spamc/spamd.
2.) migrated the spamassassin / anomy setup to a tmpfs mount
3.) turned off rbl checks (skip_rbl_checks 1)
