Service unavailable, closing transmission channel. Server response: 4.4.2 Timeout while waiting for a command

Question

I am trying to send a message and we will ever get this error:
Service not available, closing transmission channel. The server response was: 4.4.2 Timeout while waiting for command.

Does anyone know what to do with this? Because it only happens “once” and, apparently, for no specific reason.

I've seen many articles saying:
442 The server started to deliver the message but then the connection was broke(Source: http://www.sorkincomputer.net/SMTP%20errors.htm )
