"Broken pipe" means that Exim tried to write to a socket after the peer
had gone away. I guess the mail server mail.ansoniacb.com is dropping the
coonection before Exim has completed sending the message data, so Exim
gets an error when attempting to write the data and gives up before
reading any remaining responses, because the connection has gone away
unexpectedly which indicates some kind of problem. The mail server itself
is very crappy, so this kind of misbehaviour is to be expected.
