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
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
Any thoughts or suggestions welcome.
