Cyrus imapd doesn't have source ip filter feature, afaik and support
only one authorization group (ldap_filter).
With this reason you have to use some tric.

You need to configure two access groups and two cyrus servers (with
replication or murder configuration) and use different groups on this
servers.
Possible, some imap proxy can be configured for using second group.

WBR.
