My 2009 Mac Mini is in desperate need of an SSD upgrade. Unfortunately, I have close to 1TB of data there (mostly PLEX media), so upgrading the two drives would be cost prohibitive. I will probably pick up a 2012 MD388LL/A with i7 CPU at some point… I hope. The new ones are pretty much not upgradeable.
Since my website and mail server are running on Mavericks, I dare not load Yosemite on that system. Lord only knows what would happen to PLEX. It was just recently updated to solve a memory leak issue which pretty much crippled the machine on more than one occasion. I even bought an APC Masterswitch in case I had to remote hard boot the server in case my mail stopped working.
I’ve replicated most of the shell configuration from the Mac Mini Server I setup at work to the one at home. There were some pretty helpful blogs which outlined how to include command aliases in bash. This makes it real easy to execute a multi tail of all three mail server logs. I think It might be useful to consider customizing the log system on the new servers to make data mining easier. Everyone is so convinced that the mail server is broken, that I am constantly providing proof of delivery from the mail log data. It’s actually really useful when dealing with another company’s IT – especially if they’re outsourced.
I’ve got a Linux box that I’m messing around with here as well. I think I can do port mirroring on the switch and send all mail traffic to both servers. Maybe even a simpler configuration until the Linux box goes live. In either event, Mavericks handling of spam messages, (assuming you want to use spamtrainer to update bayesian filter rules) leaves much to be desired. Accounts have to be created on the system for “junkman” and “notjunkmail”. This looks ridiculous on the login screen for starters… Messages meant to be used for training must be redirected to the other accounts. This is easy for experienced IMAP users, but for novices using a PC based mail client, it may be very difficult at best.
