I am in the process of replacing our Cyrus Front-End servers with a proxy server that can front both Exchange and Cyrus IMAP, as well as future IMAP hosts as we move and migrate users. The two that stand out are: Perdition, and NGinX. I'm looking for recommendations, or experience with either, or additional suggestions to examine. Initially it will replace the old (and back-leveled) Cyrus Front-End servers in our murder aggregate, and I would like that process to be smooth and transparent. But the proxy will then be switching back-ends based on Exchange vs Cyrus hosted IMAP (Currently Exchange users are told to configure their clients with a different server, a practice we would like to discontinue.) We will also be migrating users (usually from Cyrus to Exchange, but the other direction happens as well), and we would like this process to be as transparent as possible. Finally, our Webmail server will also be using the proxy, so a proxy that maintains state-full connections would be a plus, but this takes second place to location transparency. Because of the need to host multiple back-ends based on account, I have not so far been considering imapproxy, even though this provides the state-full connections. Any thoughts or suggestions welcome. Thank You, Mike -- Michael D.
