It should but the MTA we're connecting to is a load balancer, and this
is a known issue with our load balancer vendor (the backend goes down
but the load balancer doesn't terminate the connection), but this
could happen for a variety of other reasons.
I chose to do this rather than SO_KEEPALIVE because the socket
interface isn't really exposed through the smtplib module.
