comment MySQL taking too much CPU
Well, the mysqltuner script is telling you. Your maximum memory usage is 3.4x how much ram you have, 2.7 megs per thread is really not that much, and you have a 128 meg innodb buffer pool for almost 3 gigs of data.

comment mdadm raid6 built, but no mounting or fsck
root@NFS:~# hexdump -C -n 2048 /dev/md127 |fgrep ef|fgrep 53 root@NFS:~# Thats a very bad sign. :| As far as what happened - no idea. Shut it down to replace fans, started up, and the raid was degraded. One drive didn't show up, and the other smart checked to "degraded, backup and replace", and mdadm showed the drive as failed. I pulled them both out. And, no backups of a lot of this data, as I have no secondary place to put a couple of terabytes. No idea why these failed - probably bad drives out of the batch. I'll dig into logs, see if there was something that should have altered me

comment mdadm raid6 built, but no mounting or fsck
mdadm raid 6 across unpartitioned disks, and made on a separate linux install that had to be replaced once already. Due to the root drive failing. I believe that I just mkfs.ext4 'd the entire /dev/md127

comment Messages being bounced (postfix & gmail mail servers)
The information here is probably not going to be enough to solve this issue. What we really need to look at are email headers. If we could see the code, or if you could use a tool like wireshark to capture the email sending communication, that would be very useful.
