I have a number of users who access Zimbra only via thick clients. Since these users never log into the webclient they are often unaware when their free space runs low. Is there a way to configure Zimbra to e-mail users at a certain threshold? If not, is their a command line way to get the used/free storage for each account so I could write a script to provide this notification? I'm sorry if this is documented somewhere and I missed it. Thanks!
