I'm following the steps mentioned here for integrating Mailman, but updating for use with 7.0 by using Calendar Resources instead of accounts:

ZCS Mailman Integration - Zimbra :: Wiki

My Create Command is like this:
Code:
  $ZMPROV ccr $ADDRESS@$DOMAIN $(randompass) \
    displayName $ADDRESS \
    zimbraCalResType Equipment \
    zimbraMailTransport smtp:$MAILMAN_SERVER:25
however when I try to delete the CR it fails with this error.

ERROR: service.WRONG_HOST (operation sent to wrong host (you want 'null'))

I found a post on the forum from 2007 that suggests the problem is with the zimbraMailTransport not pointing to a real zimbra server.

I attempted modifying the CR to change the zimbraMailTransport back to my zimbra MTA but the error persists.

Code:
  $ZMPROV mcr $ADDRESS@$DOMAIN \
    zimbraMailTransport lmtp:$ZIMBRA_SERVER:7025

  $ZMPROV dcr $ADDRESS@$DOMAIN
Thoughts?
