I have a zmprov script written. The only problem is when I'm trying to create forwarding addresses for specific emails, I get this error:

Code:
prov> ERROR: account.INVALID_ATTR_NAME (invalid attr name: [LDAP: error code 17 - zimbraPrefMailForwardAddress: attribute type undefined])
This is command I'm running (remember this is a script, so assume zmprov is already typed):

Code:
modifyAccount user@pdadmin.com zimbraPrefMailForwardingAddress user@hotmail.com
