13276 H=172.17.80.0 [172.17.80.0]: SMTP timeout after sending data block (155591 bytes written): Connection timed out
Problem is at the far end of the connection. You've sent 150KB of data and it's not given you a response.
To pre-empt the next question: you'll have to ask them. And if that's you (it's a private IP, after all), then you need to look at your other system.
