Question:

Failed sending DATA Command

Jun 06 '16 at 18:48

We are using Chilkat for our email service with our ERP. every now and then we get have an error "Failed when sending DATA command". We relay from our ERP to our Exchange 2010. in my SmtpReceive logs I see the email has yet to reach the Exchange to fail. Does anyone know what this DATA Command is?

Answer

DATA is the body of the email. Most likely the connection to the server disconnected or timed out. Too many pieces between the client and the server to know which is the culprit.
