Scalable Mail solution with NAS

Take a look at NetApp. My company (unfortunately) signed an NDA with
NetApp, but they've posted that Yahoo uses NetApp for their e-mail:

Rumor has it (no, I'm not violating my NDA) that Hotmail also uses NetApp.
-Plenty- of other large sites use 'em for e-mail. Just call a NetApp
sales person and and ask for the list. It's impressive. I do believe
it contains some carrier-class implementations.

We use Netapps at COLT for email.
And as I understand it, Demon Internet in the UK uses them also
and they have over 200,000 users taking SMTP and pop3 feeds.


Their stuff is state of the art for large storage, i have worked for 2
isps that have used several of them..
