Possible, but if the only think you're interested in is to allow  
webmail service to people from the 'example.org' domain, just denying  
authentication for all other domains should be enough. You can do this  
without changing the imp authentication by adding a preauthenticate  
hook in 'config/hooks.php'. See the example file.

I wouldn't mess with the IMAP server here, unless you don't want  
people to use IMAP by any means.
