addressed by disabling ESMTP pipelining. Once the SMTP client is
sending the message body only TCP/IP parameters are relevant (window
scaling, MTU, ...). In some cases subtle bugs in degraded network
equipment will be evident with some payloads and not others, so
problems can also be content dependent.
