the user@mail.dataforcecrm.com is cumbersome

Step 1
Make a new domain
-use the admin console wizard
OR
-command line (if you have no external auth it would be like):
zmprov cd dataforcecrm.com zimbraAuthMech zimbra

Step 2
open a individual user - change the drop down in the general area to 'dataforcecrm.com'
(let us know if you need commands for doing this in a large batch)

Trust us-leave the old domain-don't delete it yet!

And make your dataforcecrm.com as your default domain and add in the virtual host tab of this new domain the mail.dataforcecrm.com.

for RFC compliance too, don't forget to alias the admin account to your new domain.

hmmm.... hope this helps..
