I've been running Zimbra Open Source at home for my family happily for a couple of years now. I have been doing this with 8 mailboxes on an Intel Atom board. I just ordered the newest Intel Atom board (no CPU fan) and will be using an SSD.

I am considering using the free 10-user appliance instead of the open source edition, but I have a special configuration and I want to know if I can customize the appliance in the same way.

The most important customization is for my children. I basically setup a whitelist so that Zimbra only allows them to send to a specific list and only allows that specific list to send to them. All other attempts, in or out, get dropped. Can I do the same thing with the appliance?

Also, I customize the junk mail filter to be more aggressive, as DWTractor has posted in the forums in the past. Can that still be done?

Are there any negatives I should be aware of before doing this?
