Maybe someone could find this useful. I wrote a python script to do that, but instead of deleting account I put it into closed state in order to be able to perform archival steps prior to removal but also to protect account from bugs that could cause it to be removed (loosing all the mails) while in fact it is still active.
In the course of this, I also wrote Python class to handle Zimbra administration connections that wraps SOAP messages. It's not finished as I don't have time now, but if anyone is interested the code can be found here:
