is there any way to return the "from" address in a zmmailbox search?

Currently it just shows me the display name of the sender (not the address)...

Im having to run zmmailbox to get the message id's then put that in a loop to do a "gm" (get message) on the ID, and grep out the From:

[zimbra@angelia ~]$ zmmailbox -z -m s -l 200 -t message "to:"
num: 127, more: false

Id Type From Subject Date
