[Dovecot] managesieve proxy
We have dovecot on a pop/imap server working as a proxy to dovecot on the backend storage servers. This is working fine, but the difficulty is that if I use, for example, avelsieve in squirrelmail, it doesn't know where to connect. I imagine the same problem would exist with sieve-capable mail clients such as KMail, especially since the outside world isn't allowed to connect directly to the storage servers.
Does anyone know of a way to proxy managesieve?

There are no managesieve protocol proxies, but you could proxy it at the TCP level.
Something like tcpproxy will let you forward TCP connection to another host.
I think you can even configure netcat to do this. Of course, your proxy
machine can probably also do this in the IP stack. On Linux, for instance,
you could use iptables.

That would work for a single backend machine, but not for multiple machines.
If there's no managesieve proxies, then I imagine my best bet will be to modify avelsieve to be able to determine which backend server to connect to. In the short run, I think avelsieve also has an option to connect to a different server. That should be sufficient for testing purposes.

Dovecot supports IMAP/POP3 proxying, so I think it would be pretty
easy to update the managesieve patch (http://dovecot.org/list/dovecot/
2007-March/021130.html) to support proxying as well. Might be as
simple as just copying src/imap-login/imap-proxy.c to managesieve-
login/ and update client-authenticate.c to use it.
