We have a requirement of integrating zimbra client with an existing enterprise application at our client end.

The issue is the zimbra users should not be allowed to type addresses in TO and CC field, instead based on their role and login information, a list of valid users will come from the enterprise application which should be selected by the zimbra user.

We have already tested the same successfully in basic HTML client.

We want to move to the zimbra AJAX client. can some one help with the identification of relevant files in the AJAX version for modifications.

We would essentially like to disable TO and CC field, have new fields instead which can have valid users populated from enterprise application.
