Hi!
This two commands might be useful for you:
1)
Code:
zmprov -l gaa -v|grep "zimbraId:\|\# name\|orwardingAddress\|zimbraMailDeliveryAddress"
(sorry, I didn't get what you mean by Trainee Email Address..)
2)
Code:
zmprov gqu `zmhostname` |awk '{print $1";"$3}' (Prints out mailbox;quotausage couples, in bytes.)
Both commands must be run as the zimbra user..
Enjoy!
[EDIT: Seems I got second
