These errors are seen when the Mail Connector is not able to connect to the mail server or the connection to the mail server is terminated before the transaction completes. If these errors are seen intermittently which means they are not happening all the time, then there was a problem with either the mail server or the network connection. Please check with your Mail Admin and Network Admin if there were any problems with the mail server or the network.
