As that MTA implements pipelining, what you are seeing is the first 250 ok
from the MAIL FROM:<> ... notice that your Exim sent nameplanet MAIL FROM:,
RCPT TO:, DATA: in a continuous stream without waiting for 250 ok (which is
what pipelining facilitates).
Looks like we have the rare case of an MTA which advertises pipelining and
doesn't implement it properly, or maybe it took exception to the contents of
your bounce message for some reason?
Try turning off pipelining for that one host somehow and see ... maybe even
force SMTP instead of ESMTP, by sending HELO.
