Hi Michael,

Thanks for your quick response. I was suspecting that I might need a backend 
IMAP server to run with RCM but wanted to make sure it was an absolute 
requirement. I suppose I should have noticed the word "client" in the 
description and that would have answered my question. lol

It seems that the server specs and bandwidth aren't going to be that much of 
a problem as we're going to be using a large datacenter and have plenty of 
servers setup in clusters. Finding a good, reliable IMAP server is going to 
be a problem it seems. I'll keep looking and, if anyone happens to have any 
recommendations, please feel free to forward them my way.
