Setting the default Mail Identity

[Vimm]

For my account creation process I have a script which creates an account with an alias or two. In some cases I would also like to set the default Mail Identity to use one of the aliases rather than the main account. Is there a way for me to do this for the user during provisioning?

After much poking around I have discovered the following.

zmmailbox -z -m me@example.com mid DEFAULT zimbraPrefFromAddress alias@example.com
