Broken Pipe is the error that Exim sees on some operating systems when
the TCP/IP connection to the host gets dropped.

No, because then you would have a very unreliable mail server that would
bounce messages incorrectly. Consider the remote host dying in the
middle of a message, or the network crashing or your router crashing or
whatever. All of those appear to Exim as a dropped connection, which, as
I said, shows as "broken pipe" on some operating systems.
The foreign mail server is behaving incorrectly by breaking the
connection. It should be swallowing all of the message, and then
returning a 5xx error.
