You can also use:
cm user/chris@virtualdomain1.dom
cm user/chris@virtualdomain2.dom

The only tricky part to this setup
is that to create/modify the password
saslpasswd is run with the -u parameter as:
saslpasswd -c -u virtualdomain1.dom chris
saslpasswd -c -u virtualdomain2.dom chris


This will allow folks to login using their
email address as their ID which I find
reduces a lot of exlanation/confusion about
why they're different.
