[Dovecot] use Alternative Storage as a cloud mail service

[♥ NiNJA ♂]

Hi all

I'm trying to create a mail service provider

I like to know is it possible to have some servers as storage servers
And automatically put email datas on the servers
Something like having 3 servers , If server two get full , Automatically
use server three

If it's possible give me some solutions to use

I like to use CentOS OS on my servers

Thanks in advance

Hi guys
I like to know is it possible to create Unlimited number of email accounts
with Unlimited Storage in each email ?

Does anybody do it ?
Does dovecot good enough for having more than millions of users ?

Thanks :-)
