SMTP Server Connection Refused

After it was working fine for couple of weeks I suddenly get this error:

No connection could be made because the target machine actively refused it 127.0.0.1:25 : at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)

Any ideas what could have changed?

Do you get SMTP greeting message? telnet localhost 25

NO => local SMTP server is not running OR it rejects new SMTP connections due to overload OR some static or overload protection rules of local firewall blocks your smtp connection
