    Default Trouble relaying email after migrating accounts from one ZCS server to another

    I'm practicing (and will be doing in a production environment once all of the kinks are worked out) moving a domain's email from one ZCS server to its own ZCS server. Both servers run 7.1.3 on RHEL6 x86_64. Here is my procedure so far (which seems to work fine), minus the changes needed with DNS, etc.

    1) Mark all accounts in the domain as closed.
    2) Perform a full backup of the accounts using zmbackup.
    3) When backup is complete, use NFS to mount /opt/zimbra/backup on the new server.
    4) Perform a restore of all of the accounts
    5) Change the mail transport each account as they're restored (/opt/zimbra/bin/zmprov ma $account zimbraMailTransport smtp:psi-mail01.twtc.marianinc.com:7025)
    6) Set all accounts as active on new server
    7) Recreate all distribution lists
    8) Test sending email from user to user (within the same domain) on the new mail server
    9) Test sending email from user to external user
    10) If all is well, delete the accounts off of the old mail server

    The problem I have is step 8. Below is a paste (with redacted user/domain information) of /var/log/maillog on the new mail server.
    Code:
