backends with different altnamespace in a murder configuration

[Jean-Christophe Delaye]

Hello,

We are currently running cyrus 2.4 in a murder configuration: 2 murder
servers (master and slave) and 5 backend servers.
As in 2.x version, the altnamespace value is set to its legacy value
:off on all the server's imapd.conf.

We would like to change the altnamespace value to on BUT only for some
backend servers. The idea is to have a better integration for specific
users depending of their mail clients.

My question is: Is it possible in a murder cluster configuration to have
backend servers with different altnamespace settings. If so, what is the
impact of the murder servers altnamespace value ?

Greetings.
