We're running this software now. It save a lot of effort on the IMAP server by eliminating the constant start-up/tear-down of IMAP daemons on the server. One thing though I've found with this software is that if the IMAP server is not up when you fire up the proxy it'll hang.

I'm trying to see if our IMAP administrators want to support this feature to reduce the chatter generated by filters, but so far I haven't gotten anything out of them on this (In academia, the politics can be vicious, and with email being such a critical component here the politics are extremely vicious.
