Send to... Mail could not be sent

Hi All,

I have a strange problem with sending out emails from KM Content with Send to...

Warning: Mail could not be sent

DefaultTrace file:

EmailChannel: SMTP error while connecting to server for INTERNETCould not connect to SMTP host: hostname.abc.com, port: 25;

  nested exception is:

     java.net.ConnectException: Connection refused: connect javax.mail.MessagingException: Could not connect to SMTP host: hostname.abc.com, port: 25;

  nested exception is:      java.net.ConnectException: Connection refused: connect      

I am able to see subscription notification in my notification iView, and connect successfully via telnet (telnet hostname.abc.com 25) with emails being sent to outlook.

Config are as follows;
