If enabled, a specific IP will be bound when performing a client
connection.  **client_bind_name** is used if it is set, otherwise
**servername** is used.  This is useful on multi-homed servers where Cyrus
should not use other services' interfaces.

If not enabled (the default), no bind will be performed.  Client
connections will use an IP chosen by the operating system.
