We have stopped receiving email alerts after our PO server (NW 7.4 single stack) was restarted recently. The CBMA functionality had been working fine since long until recently when restart had to happen to update an adapter.
Although alerts are visible in Alert Log (attached), the emails are not coming to our mail boxes. CBMA settings are in place. Are there any services that might have stopped or not started properly when PO server was restarted? What else should I check?
