[Linux-cluster] IMAP server clustering ...

[Michael Gale]

Hello,

	I looked into it and it is a great solution in my mind, but the problem 
there is the number of servers you would require. We are very limited 
for space in the IDC (about 1 rack left) and we want to be able to host 
30,000 plus users worth of e-mail.

So at the moment due to space restrictions either a shared storage or 
out sourcing e-mail are the only options I can see.

Michael.
