I just finished upgrading Group Wise 2012 to Group Wise 2014. After the update I went to the administration Console and I see a red x next to the MTA icon. When I look at the red x I see MTA Not Running http://serverip:0. When I click on the MTA icon and look on the general page it show running. Mail does seem to be going through the mta so I do not know what the issue is.
