For some time now the Aras server has ceased send emails. No errors (even if I set wrong value to "Mail SMTPServer" parameter to InnovatorServerConfig.xml). No connection attempts in the mail server logs. But the emails to be sent appear in the "Innovator\Server\temp" folder on the server. But nothing else happens. It looks like the server is not trying to send them.
What can be wrong? Aras 12.0 SP9 free.
