Amazon cloud *IS* outsourced mail, Amazon has access to your virtual 
servers and it passes without VPN into their network.

20K users with 20G each = 400 TB. With zfs compression perhaps 300 TB.

How much does it cost to use 300T redundant fault-tolerant storage in an 
Amazon Cloud?

Google Mail does use your text patterns in your mail for advertising. 
That's the way you're paying them. And they don't restore your mailbox 
unless you use a business contract which means costs for each mailbox. 
There's no such thing as a free lunch.
