Nginx IMAP/POP3 Proxy Connection Pooling

We're going to be using nginx to do imap and pop3 proxying. As some of
you know, we are the the mercy of the mail client as to the number of
connections that we will see from a user's client. In extreme cases, if
a user has 40 Folders, their client will create 1 connection for each
folder. In this situation, we'll see 10s of connections for just 1
user.

I couldn't find any config settings to setup server-side (backend)
connection pools. I'd love to set up nginx so that I get 1000s of
incoming/client connections, but only a fraction of that to the backend
mail servers. My goal is to avoid the 1:1 ration of connections.

Any help is greatly appreciated!
