comment Forward all SMTP traffic to anti-spam server except for authenticated SMTP?
Correct. I do not need to worry about the spam. I have updated the question. I cannot fully reject unauthenticated connections on port 25, as the anti-spam filter will pass the clean messages on without authentication. I do not know how to configure qmail to reject all unauthenticated messages except from a specific IP, which I believe is what I specifically need.

comment XenServer Linux guest booting off iSCSI SAN (ZFS storage): Will a non-checksumming guest file system still be at risk?
(Thanks for the advice, btw! I definitely have a plan for backups, but I'm also trying my best to avoid known points of failure, common or obscure.)

Wow! So if a guest file system is always at risk for corruption, would NFS directly to the NAS file system be immune, or at least only subject to file-by-file corruption? I'm trying to virtualize several NAS boxes for privacy (and cost) on top of a physical NAS--complete with all the redundancy you recommend. I need the best solution for data integrity, while keeping the virtual NAS boxes separate so each group of users has complete control over their own NAS. But the files don't have to live inside a virtual file system if that is more dangerous vs NFS from the guest to the phys NAS.

comment Rack Storage - Backplane with 20 SATA connectors or backplane with 5 Mini SAS connectors?
Thanks for the feedback. I ended up picking the all-SAS option, because I found there would be no performance penalty as each channel on the SFF-8087 cable would offer 3 Gbps equivalent to SATA2 (and faster SAS is available with mini-SAS HD cables). The choice between all SAS or all SATA really depends on the controller hardware chosen (ex: expensive 20 port SAS controller vs 8 onboard SATA connectors + 8 port SATA expansion HBA).
