Yes, the GnuTLS library produces this somewhat obscure message when
a read it's trying to do on the underlying TCP socket returns an
error to it. The error can be, and most often is "the far end
closed the TCP connection" when GnuTLS is expecting a proper, graceful
notification that the TLS layer is being closed.

So long as the mail message was apparently transferred properly you
can ignore this one.

Your debug shows SMTP-leve success responses for both the data
phase for the message and the SMTP QUIT after it.
